Audit Mode
In Audit mode , PK is not present. BIOS does not authenticate programmatic updates to
the policy objects, and transitions between modes.

image Execution Information Table, but approves the images whether they pass or fail
verification.

the BIOS performs signature verification on programmatic attempts to update policy
objects.
Deployed Mode restricts the programmatic mode transitions.

Secure Boot
Custom Policy
