There is a mod that allows for dynamic bone collisions but like anything that modifies the client it is against TOS. It *probably* won't get you banned, unless something screws up (recently there was a bug with one of the mods that spammed reconnect attempts and got a bunch of people 3day bans) or you literally scream in a moderator's face that you're using a hacked client.

It likely won't be around for long, as the entire mod framework will have to be rewritten for unity 2018 if VRChat ever (they say 'soon') updates to that.
