Is it advisable to install the 5.14 RT RHEL kernel on a server running RHEL 8.6 OS?

I attempted to upgrade my x86_64 Intel server running RHEL 8.6 to the 5.14 RT kernel from RHEL repositories, but encountered SSH connection issues and unresolved dependencies despite trying SSH RHEL-9 dependency packages. Is it advisable to upgrade only the RT kernel to 5.14 on RHEL 8.6?
