Title:
  Grub allows to load unsigned kernel even BIOS enabled secure boot

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  The grub 2.02 in bionic still has the insecure commands which "linux"
  and "initrd", it allows to load unsigned kernel and initrd.

  Even BIOS has forced the secure boot, when grub boot menu shows and
  stay few seconds and it allows to enter to grub command-line by press
  'c'. In the grub command-line, that's easy to load unsigned kernel by
  'linux' and 'initrd' commands.

  Suggest to remove the 'linux' and 'initrd' from grub commands list.
