Don’t ask me why but I decided to see if I could build the latest version of Hyperion.ng to work with CoreElec 21 running on my Ugoos AM6b+. It works, if anyone is interest here is the addon zip archive to install in kodi and below is the git patch for the small number of changes needed to get it to build as well as the Dockerfile for the build environment.
