Depending if you need LDP for anything else, you could set up the TE
tunnels you want with 'mpls ip' but NOT set 'mpls ip' on your physical
interfaces.  This is an analogue to one-hop primary tunnels for FRR
support, and the directed LDP session that the ATOM xconnect runs over
will only run over a configured tunnel.  I can think of all sorts of 
reasons why this might not fit though, and the 12.0S preferred-path
feature is much more specific.
