efi0 - usb install boot vs main disk boot

Hello,

I am trying to figure out a problem with my UEFI boot not working
anymore using snapshots. I am able to UEFI boot from USB install disk,
but at first boot from the main disk the sequence stops at efi0 entry.

Can someone, please, explain why efi0 is not detected on boot from the
USB install disk, but it is woken up at boot from the main disk? Is it
needed? Can be disabled?
I see UEFI stuff receives no answers on misc@, is it because it is
such a random thing from the vendor?

Thank you.
