Option Heading
Secure Boot Key Management
Lets you manage the custom key settings.
Import Custom Secure Boot keys
Default is disabled.
Clear Secure Boot Keys
Lets you delete any previously loaded custom boot keys. Clearing keys will disable secure boot. Default is
disabled.
Reset Secure Boot keys to factory defaults
Default is disabled.
Enable MS UEFI CA key
