Kernel builds in CBS should work, we did a PoC a while ago in
Hyperscale at https://cbs.centos.org/koji/taskinfo?taskID=2476549
though we still need to productionize it. However, you will not be able
to sign them, so Secure Boot won't work properly. See
https://pagure.io/centos-infra/issue/307 for that.
