Hi,
Once you use autoroute announce, the TE tunnel looks to IP like a new link for all the destinations behind the tunnel endpoint. From this point of view your question could be rephrased to: "How can I avoid to send IP packets towards a certain destination over a particular interface?"
You can use
1) static routing
2) Policy based routing
3) class-based tunnel selection
4) make the tunnel worse than the IGP path (e.g. with relative metric +1)
All have their pros and cons depending on your specific network requirements.
Hope this helps! Please use the rating system.
