No. Once again: the NIST PQC competition is a project to standardize post-quantum cryptography constructions. It's not a protocol competition, any more than the AES and SHA-3 competitions were.

This is literally spelled out on the competition page. I'm having trouble how anyone could have any confusion about this. It literally says: do hybrid systems if you want, that's outside the scope of this competition.

How would it even have made sense to pursue hybrid systems in this competition? Like how would that have actually worked?
