You can self host ZeroTier controllers, which are the things that control network access. See the controller subfolder of github.com/zerotier/ZeroTierOne. Roots in ZeroTier are harder to self host right now (it’s getting easier in the future) but they are just dumb STUN/TURN equivalents. They have no power to grant access and can’t even see what networks you join or what you are doing.
