How to turn off drl

please don't use abbreviations like 'Drl'. Only you know what it means. 'Daytime Running Lights' is worth typing in full. It is part of the Body Control Module according to this

Are they burnt out

There is no DRL module .
Daytime Running Lamps (DRL)
The DRL are a function of the front turn signal lamps. The DRL will operate when the ignition switch is in the RUN position, the gear selector is not in the PARK position, and the headlamp switch is in the OFF position. When the BCM receives these signals it will signal the turn/hazard flasher module to turn on the DRL by grounding the DRL low control signal. The turn/hazard flasher module supplies voltage to the DRL on the right and left DRL/turn supply voltage circuits. If a front turn signal lamp is inoperative the DRL will not operate.
The DRL can be deactivated by turning the headlamp switch to the DRL OFF position while the DRL are operating. The DRL defeat position of the headlamp switch is a momentary ground signal to the BCM to command the DRL function ON or OFF. After each key cycle the BCM will default to the DRL ON function.

DRL has nothing to do with the truck shutting off. On some years there is a separate fuse labeled for DRL. In later years the software can be changed disabling the drl, however you may not find anyone willing to do so due to liability concerns with deactivating a safety feature. Sounds like you need to find a better mechanic...one who can diagnose the issue rather than throw random parts at it while hoping for the best.

Well the drl would not affect the turn signals, and you should be able to turn the parking lights on from the switch.
Do you have power on the signal and parking light fuses ?

[Information] For a 2002 Toyota Camry, the Daytime Running Lights (DRL) operate utilizing the High Beams (inner Lamps closer to the center of the vehicle front) at a reduced power.

[The troubleshooting process:] Review the Owner's Manual and ensure the test configuration matches the following criteria:
1. According to the 2002 Toyota Camry Owner's Manual (Check your Owners Manual):
"The DRL system will make your headlights come on at a reduced brightness when:
The light switch s in the "DRL" position.
The ignition is on with the engine running.
The headlight switch is off.
The parking brake is released."

2. Set the Test Conditions according to Step 1 above.

3. Check the headlight bulbs to ensure they are not burned out. If one burns out, there is a fair chance that the other would have burned out at the same time. Replace as necessary. In this case, if the high beams operate, the DRLs should also operate.
4. Test the system, ensuring the step 1 conditions are set. (Engine running, Multi-function Switch on Turn Signals in "DRL" position, headlight switch off (repeating what the manual says -- it should be obvious that in the "DRL" position, the headlight switch should be off / do not have the switch positioned to "High Beam"), and the Parking Brake "off").
5. If DRL lights do not work, check the engine compartment Fuse and Relay Box. there is a 5 Amp DRL fuse -- replace it with the spare. Test (step 4).
6. If it does not work, swap around or replace relays -- there are three (3). Any one of them could be bad (stuck or burned out). Test (step 4).
7. Other less likely possible issues could be that the Multi-function Switch is broken or a connection / wire is broken. [Beyond the scope of this process.]

My problem was that the test configuration did not have the engine running and parking brake off - Step 1. Problem solved with much thought, repetitive tests on the vehicle and going back to the basics -- what does the Owner's Manual say and where are the applicable fuses and relays located?

If it is anything like my 04 GMC Sierra, there is a relay panel under the hood. In that underhood box where you found the fuses, there are also relays. They pop out (the diagram is on the lid of the box). After the GMC hit 200k, the relays started going out. The high beams are on a relay, the lowbeams are on a different one. You can pop one out and replace it with the horn or foglight relay if you want to check it out. I am betting that the DRL bulb just happened to go at the same time. Mine go out regularly..I would say around every 10-15k miles. I don't know if this helps, it is just something that I have run across with a similar vehicle.

With the Key in the RUN position, check for battery voltage on the brown wire in connector 2 terminal H at the DRL module. Also check for battery voltage on the pink wire terminal C of the same connector. if you see battery voltage, then the IGN switch and the two fuses supplying power to the DRL are working fine.

Next, check the brown wire in connector 1 terminal H at the DRL module for battery voltage

change the headlight switch!! itself its broken inside the unner contacts
