Just posting this here as there wasn't a whole lot of info on how to do this on the newer trucks. I've been wanting to completely disable it on my 2021 GMC Sierra but all I have found was a YT video on how to unplug the antennas, which is not the best method as it's still active, collecting data and can still connect to a cell tower if close enough to it.
Found the fuse that totally disables it, which also disables the built in GPS. It's a 10A fuse called TCP. In my case, it's in position #42. Pulled it and the OnStar button doesn't come on or activate when pushed, the on-screen system says it has a connection error and the GPS symbol at the bottom of the screen has a red slash across it. My phone can still connect to the system via Bluetooth and use Android Auto.
Reasons for doing this are varied. I have read some stories that GM may be selling/sharing driving info to insurance companies and may also be collecting data to follow owner's driving habits. There is also speculation that when you connect your phone to your vehicle via Bluetooth, it can also collect data from it. I don't use OnStar so I'd rather not have it at all.
