The ClearPass appliance does not provide access to the operating system and should be considered 'an appliance' instead of RHEL.
Check here: This release changes the underlying base Operating System (OS) from CentOS to Red Hat Enterprise Linux (RHEL) 8.x. The system continues to be hardened and maintained by Aruba R&D team as previous OS versions have been. This is still not considered a RHEL distribution OS despite the change.
