It is true that the videoinfo module cannot be loaded under SecureBoot
mode.  Your bug report does not explain why you need to load it when
SecureBoot is on.  As the name suggests, this is an informational
command only.

Title:
  grub doesn't load videoinfo with secure boot enabled

Status in grub2-signed package in Ubuntu:
  Incomplete

Bug description:
  When I enter grub, whole interface is really unresponsive and rendering is visibly slow. This is not new issue, so I was invastigating why is this happening. When I enetered grub console after reboot and entered 'videoinfo' command, grub answered 'Secure boot forbids loading module from hd(...)...videoinfo.mod'.
  When I disable secure boot, everything works as expected.
  While I am using dual boot with windows 11, I need to keep secure boot enabled, so the only solution from my point of view is to add videoinfo module into 'grub-efi-amd64-signed' package.
