Car remote kill switches currently work on LTE/4G/5G, cellular network, which is a cable that generally goes from a device in your dash via a wire snaked through your vehicle, and comes out the antenna to connect to the network. All you need to do is find that LTE/4G/5G coax cable and disconnect it, and then it's useless.
While physically yes, until/unless the onboard system is programmed to disable or lock down the vehicle if the antenna is unplugged or the shutdown feature otherwise becomes disabled. Fairly simple to impliment.

Only way to know is to try.
Even that can be faked out with a 50 ohm resistor and the system won't know the antenna is unplugged.
HAM can confirm
Good to know.
