You should not be swapping out the scheduler on RKE2. Honestly RKE2 is supposed to be prepackaged and opinionated k8s (everything just works and is tested out of the box) in a supportable format. If you want to modify core kubernetes components it might be best to use a distro like upstream kubeadm or even k8s from scratch.
