For FBT you need lighthouse tracking which the G2 doesn't support natively, and pucks. There are hacky ways to do hybrid tracking but it's a faff and you need to buy the lighthouses. You also need to calibrate the two playspaces which leads to your trackers being slightly "desynced" in space relative to your headset sometimes.

That said the only real use for trackers is VRC, so if you're completely against that it's kind of a moot point.
