Sounds like the switch has failed as it works all of the lights in and outside of the truck in conjunction with the bcm if you want to leave the battery connected and have the lights off pull the parking and headlight relays till you can replace the switch
If you want to disconnect the headlight switch
Do this on flat ground if you can
First put the truck in 1 and lower the steering wheel
Next remove the dash bezel
Next the switch I think it pops in place but check for screws first

If that don't work check to see if the sun load sensor on the dash isn't covered
