Yes, although it has been supported for nearly two
years, but there are still many dependencies
against RHEL 9 kernel (5.14) codebase.

Actually, the PR below has been delayed for
months:
https://gitlab.com/redhat/centos-stream/src/kernel/centos-stream-9/-/merge_requests/4123

I think it's not quite easy to just cherry-pick
random commits due to twisted codebase cleanups,
rolling the codebase to upstream v6.4 is a good
choise for RHEL 9 long term maintainence.

On my side, I could even help submit these
backport, but I have no idea why the PR above is
still delayed.

Thanks,
