This will always be a game of cat and mouse, but I know that for example 3rd gen tacomas have a module that does all the talking (has the SIM card). You can pull a fuse and it kills it, but you lose your Bluetooth microphone also if you connect your phone and want to make calls - however it’s just a power passthrough so it’s really easy to splice a bypass cable that gives power back to the microphone in the cab.
There’s other stuff you can do, like disconnecting the antennas but supposedly if there’s a good enough cell signal the traces on the PCB will still transmit, I dunno.
Either way, there’s ways to get around a lot of the invasive stuff in modern vehicles but it gets harder every year.
