is it possible to configure an IPv6 interface to advertise its prefix WITHOUT sending a default route along with it?

No, it's pretty much going to send it regardless.

However, you can set the lifetime for which that advertisement's default router is useful to 0, and the hosts should interpret that to mean that advertisement should not be considered for default routing.

Alternatively, if your hosts support the DRP extensions, you can modify the preference level that the routes are sent with.
