Well sure, my Leaf has that also. But that assumes a level of trust that it actually fully disables everything and doesn’t have “exceptions”, and that it won’t get re-enabled during service or battery changeout or something else like that.

It took me all of about 20 minutes to remove the SIM chip from my 2015 Leaf, following a youtube video that showed everything step by step.

AFAIK, all cars before 2021 still have physical SIM chips, so easy to remove and disable the telematics.
