They could’ve unplugged it as part of servicing your vehicle.

If you don’t want someone to drive or joyride your car service it yourself, no dealership can guarantee your car won’t be driven in ways outside of what you consider ok, whatever that is as it is subjective. I worked at a Bmw dealer previously, while I havent Beaten anyone’s car I definitely Have seen people that do, people that can’t quite drive a manual and people that just don’t treat a car the owner will. There’s not much you can do.
