Okay, seriously though, it's easy. Go setup a RedHat account. Then go to
developer.redhat.com and do that flow. I don't immediately remember what that requires, but it's fairly straightforward and free. I only have to revisit that flow once per year, and I have trouble remembering what I did last week.
You can then navigate their site and download the RHEL iso and create a VM from it. During the setup you can register your VM, or you can do it later from the CLI.
Let me know if you have any issues.
