But then I took actions to attempt a workaround based off of a forum post which described the same issue.
It included: backing up and deleting the BOOT and Fedora EFI shim, performing fwupd update on the USB hub (which now ran successfully), and then restoring the EFI files.
However, after a reboot, it looks like SecureBoot could detect the changes were performed. I believe SecureBoot is working as expected due to my changes performed in the EFI.
Preferably, I am looking for a way to reset the state of SecureBoot. Or reformat the boot and boot/efi partitions, possibly via Anaconda. But I have not found a straight forward way to do that without a clean install.
