Well I performed 2 downgrades. On the 2nd one it totally hung, saying 100% done and will reboot. It won't. Even holding the power button does nothing.

Sorry to hear that. I usually find the opposite is true... Newer
machines need the UEFI updates to get wifi working correctly.

I believe you can use fwupdmgr to remove the firmware update. I think
you want `fwupdmgr downgrade [DEVICE]`. I believe you can show the
devices with `fwupdmgr get-devices`. But for the downgrade, you may
get a numbered list, and only need to specify a number.
fwupdmgr is not well documented. The man pages suck, and there's not
much info out there on the web. The best questions/answers seem to
happen in the fwupdmgr bug reporter in GitHub. The next best set of
docs is from the --help option.
