Need help with nocarjack script

Hi, im making an fivem rp server and i dont want people to steal vehicles from npcs and parked vehicles…
The script works great, but is there a way to dissable it from locking vehicles the car dealer spawns and so on and that you have like a chance to steal a npc car.

If anyone know how to fix one of these or both i would realy appriciate if you could help me!
Thanks
