On some cars you can pull a fuse that goes to the cellular modem, like many Fords at least up to around ‘21-‘23.

On others you may need to physically remove the modem if the fuse is going to more components.

Not sure about GPS but yes, some cars lose features when you do this. Can’t believe automakers dropped remote start from the fob just to push people to pay for a monthly subscription.
