What I'm hoping I can do is disable the ability to set up these

internal machines over non-SSH protocols via the SSH gateways.  In
other words, I'd like to allow forwarding, but only in one direction.

Not possible. Even if you manage to disable the built-in TCP
forwarding, the users would still be able to use separate tools to
forward network traffic over the terminal connection. You're only
making it a little bit harder for them.
