Short version (long versions are in ithe document)
RHEL 7.x and 8.x aarch64 releases are incompatible with Apple Silicon. There is nothing you can do to work around this. RHEL 9 fixes this incompatibility.
RHEL 9 will run but requires a workaround. See the unofficial Tips and Techniques document for a procedure to get it working.
