You can turn that off in the Garmin Connect App.
More (lower right) -> Safety & Tracking -> LiveTrack -> three dots on upper right -> Settings -> Group Track -> Off.
Note that LiveTrack requires Garmin Connect Mobile running on a cellphone and internet access.
There's a function called Group Track, it connects other compatible Garmins on a ride using LiveTrack and tells you where other riders are located. So obviously a cell connection is necessary.
