It’s not recommended to mess around with Tor Browser settings and its really not a good idea to do this through Tor Browser unless you dedicate that TBB install strictly to Trezor. That being said, if you are that concerned about IP leakage, just use it inside of a Whonix workstation, then you get guarantees(or at least as reasonably close to a guarantee as you can get).

Not sure, but another reason to use Whonix, since it will all be virtualized in a hardened, fingerprint resistant, and leak-proof box.
