Yeah, I do this for Babel:

protocol static babeldef6 {
        ipv6 sadr;
        route ::/0 from 2axx:xxxx:xxxx::/48 unreachable;
}

protocol static babeldef4 {
        ipv4;
        route 0.0.0.0/0 unreachable;
}

Just make sure you filter it out from your kernel protocol, so Bird
doesn't *add* it to the kernel routing table...
