Are there any resources available for locating and disabling on-board SIM cards/GPS in modern vehicles?

Title. I've ask mechanic friends and they said to expect in dash features to be busted if you pull the parts, but I suspect Faraday caging it could be a solution. I know there's only so much to be done about data being collected physically from the vehicle, but at least preventing it from being sent off remotely would be a win.
