The UEFI shell is an application that can be run in a UEFI environment

Wouldn't it be nice if you could just reference your signing key in FDF or

Boot options is different from executing an EFI image.
If you create a boot option and add it to BootOrder, the boot manager will
execute it for you.
If you want to immediately execute an EFI image and you have the device
path or a pointer to the file, then you use LoadImage() and StartImage().
