Look at fleet trucks. Usually you can get them with any bs. Like even no ac, just a frame, body, and powertrain.

Also fancy electronics like that are pretty easy to disable hardware wise. Break a cap in the voltage regulation, break a few pins of a IC, anything really that functional kills it but still let’s everything else think it’s there or there a problem it has to ignore. Like microphone modules, I shove a pin it and scramble it then fill it with CA glue. Hardware thinks it’s there but it ain’t doing anything.
