yes and no, you can add config snippets based on the device name to apply
different XKB models and rules. for more info and examples, see
https://fedoraproject.org/wiki/Input_device_configuration

however, in this particular case you'll run into two issues:
 - I don't know off-heart if there are any xkb options that do exactly that.
 - if you're using e.g. GNOME, it will overwrite your settings with the
   session-configured xkb layout. so you'd need to disable the keyboard
   gnome plugin, or apply it manually.

you can also do it at runtime with setxkbmap, that supports a device id
(again, provided there's an xkb option for it)

Cheers,
  Peter
