This function provides a platform-specific method to detect whether the platform | |
is operating by a physically present user. | |
Programmatic changing of platform security policy (such as disable Secure Boot, | |
or switch between Standard/Custom Secure Boot mode) MUST NOT be possible during | |
Boot Services or after exiting EFI Boot Services. Only a physically present user | |
is allowed to perform these operations. | |
NOTE THAT: This function cannot depend on any EFI Variable Service since they are | |
not available when this function is called in AuthenticateVariable driver. | |
@retval TRUE The platform is operated by a physically present user. | |
@retval FALSE The platform is NOT operated by a physically present user. | |
