574 MB is available in /boot/efi to install 11 MB, this should not be a problem.

How to make dnf see that plenty of space is available?

Can we see the output of findmnt /boot/efi

I may have an explanation.

For some strange reason, Fedora chooses the HFS+ format for the EFI system partition (I am using a Mac but Ubuntu boots fine with the FAT format and the Mac OS does not care so absolutely I do not see any reason).

Yesterday I installed Mac OS on another partition. By the way, in Mac OS Disk utility, I turned on journaling, and I suspect that this applied to the EFI system partition as well, making it not writable for Linux, so that Grub update fails. Just the error message would be misleading.

All this needs to be confirmed.

It is definitely mounted read-only which is probably the problem. As for why it is mounted read-only, your theory could be correct. Maybe see if there are any mount errors in the journal.

That is confirmed. Using MacOS diskutil disableJournal force I could disable Journaling on the EFI system partition. Rebooting Fedora, I could update grub2.
