I'm trying to assess the UEFI implementation of this board please.

I like the concept but:

- can secure-boot be turned off by a user?

- can the board be set to legacy BIOS mode?

- If I can use EFI-Shell, what's to keep malware from doing so, perhaps by corrupting the shell file?

- Does UEFI secure boot or other settings just do boot/driver control or does it participate in media DRM?

- will my UEFI ever be updated without my okay?

- can I back it up? Can I repair it if corrupted?

- is it a full UEFI on this board? What version approximately?

Thank you very much!
