RHEL8 is currently running python-3.6 (according to google). So, it might work. But I would not be surprised to find that an adjustment or two might be needed for the older packages in RHEL8.
The installation steps should be the same as fedora (RHEL is based on fedora) found in the README. In particular you will want to check the list of "Requires" packages found in the config/gfe.spec file and make sure they are installed before attempting the build.
