Disable injectors- a safe short-term security option?

[CraigComet]

M150 - sorry for the basic question, but where do you disable the ignition? (Which screen is this found, and is it as simple as toggling something from enable to disable?)
I'm having the car towed to a trim shop and don't want the engine to be able to fire up while it's there.
Thank you!

The Engine Run Switch will disable the ignition. Consider changing the mapping of the switch to always off regardless of position.
