Long Kwok,
Here is a config and link that permits conditional setting of the attached
bit. I wonder if something along these lines would help.

Subject: Filtering/Poisoning ISIS injected 0.0.0.0/0 default route from L1
internal routers
Hi,
I have been trying to filter out the automatically injected 0.0.0.0/0
route that the L2 border router injects into its L1 internal neighbors
as I guess it would be considered cheating on lab and you cannot do that
I was trying to filter via distance 255 under L1 routers isis router
process but not working. Here is what I tried.
Router isis
Distance 255 0.0.0.0 255.255.255.255 1
Access-list 1 deny 0.0.0.0 0.0.0.0
