logic for 60-rke2-cis.conf needs to be revised to support Tarball install on RHEL. check to see which exists:
/usr/share/rke2/rke2-cis-sysctl.conf
or
/usr/local/share/rke2/rke2-cis-sysctl.conf
and copy that file.
While you're at it, the reboot logic should probably be blocked to a single node at a time.
I think it already does what you're asking. There is one copy
here for yum installs which comes from /usr/share/rke2/
and another
here for non-yum which come from usr/local/share/rke2/
