Check if user is in full-body?

Is there any way to check if a user is using full body (or even just if they have more trackers than just hand controllers) using udon? I can’t seem to find any API for it and the API to get tracking data just seems to have handcontrollers and head.

wait, why do you need to “check” if a user is using full body?
if it’s for a world, just make a prefab for vrchat fbt, and one for half body,
and make them choose?
if it avatar, it doesn’t matter.

It’s for a world. Making them choose is what I’m currently doing, but ideally it would be able to default intelligently like you can by checking if a user is in VR when you want to make behaviour differ based on that.
