In the routing options on my etrex there are the following options:

Type car/hgv/pedestrian/bike...
Avoid
- turnarounds
- toll roads
- highways
- unpaved roads
- carpool lanes

As the flags for type, turnarounds, toll roads, highways should be 
known, the last bit could mean unpaved or carpool lanes. Have you tried 
this options?

(By the way: 'Avoid Highways' does not work as expected on my unit, it 
leads to problems on inter tile routing.)
