There is one but it's pretty buggy at the moment and can make every dynamic bone stretch in one direction. Put the installer in the vrchat game root folder and run the installer then put the .dll into the Mods folder it creates.
You can't toggle in the menu with this one either so you have to remove the .dll from that folder to stop it and restart the game. There's also an update for it somewhere but dunno where.
