Only by running separate sshds on all network interfaces.

The better way to do this is AllowRootLogin without-password or AllowRootLogin forced-commands-only, then generate a public/private keypair for the vendor and restrict what they can do with the "command" option in ~root/.ssh/authorized_keys.
