(dbx). When the default Secure boot keys are loaded, all the Secure Boot keys’ state

Allows you to delete the PK from your system. Once the PK is deleted, all the
system’s Secure Boot keys will not be active.
Load Default PK
Select Yes to load the system default PK or select No to load a downloaded PK
from a USB storage device.
The PK file must be formatted as a UEFI variable structure with time‑based authenticated
variable.
