I also started to get this error after 4/9/24 update and my windows 10 pc's mb is not secure boot optional. It does have uefi but not secure boot; the only way I could figure out to stop error was uninstall update dut don't want to really do that. Is there another work around to stop the logging or will it affect my pc at all, thanks.
You can prevent specific logging of certain events with a registry tweak but I don't know the guid after the fact I've already blocked it. There could be something more to the issue so you might want to hold off on hiding it for the time being, not to mention registry tweaking can be dodgy if done incorrectly.

If you pull up the event viewer and make a note of the Guid within the Details tab with System expanded, I can help with preventing the log, if you really want to. Make a backup beforehand, though.
