It is not a use case that has an easy solution within the confines of rpm/dnf right now, though the simple way to do it would be to write up repo builder script that grabs the latest build daily if it has changed. If kernel-debug exists, delete the non-debug packages, otherwise keep the base packages, run createrepo and add a dnf config for kernels from that local repository.
