  Sure.  See raddb/sites-available/originate-coa.

  Uh... you could send FreeRADIUS a Disconnect-Request message.  And
configure FreeRADIUS to proxy it to the NAS.  That will work.  See
raddb/sites-available/coa

recv-coa {
	...
	update control {
		Home-Server-Pool := nas
	}
	...
}

  You will have to set up a home server && home server pool for the NAS.
 This is because the CoA port is 3799, not 1812.  And, the NAS is acting
like a home server in *receiving* packets, instead of *originating* them.

  It's a bit annoying, but it follows the same proxy configuration as
normal packets.  Perhaps in a future version we could just add "proxy to
client" functionality.
