If you are still using CentOS 7.9, it's time to convert to Alma 8 with the free centos2alma tool by Plesk or Plesk Migrator. Please let us know your experiences or concerns in this thread: CentOS2Alma discussion
Sorry for unchecked suggestion. Really, we have already submitted corresponding request for adding this functionality. I have updated it with your request and I hope it will be implemented soon.
