Older Toyotas also had a DCM fuse, and this was the easiest way to get rid of telemetry. I am not sure if partially disassembling the dash and physically removing the DCM is now necessary.

There's still a fuse for the DCM even in this car but:
- It has an internal battery and will keep running for quite a while after pulling the fuse. This is a safety feature in case you get in a crash that disconnects the 12V battery
- It will break your in-car microphone as discussed. Repairing that requires opening up the dash
- That won't do anything for disconnecting the GPS antenna
GPS is receive only. If you've disabled the ability to send telemetry, there should be no reason to be concerned about the GPS antenna.
If it keeps collecting telemetry it could upload it later if it ever gets the chance. Better it isn't collected in the first place.

My Ford ~(2018 era SYNC system) has GPS and Bluetooth but no cellular modem.
It still technically is used for telemetry... but only when you get into a wreck. It'll ping the onboard GPS at that time for coordinates, then place a voice call over your paired cellphone to 911 with TTS coordinates and information about the wreck.
