| 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. | |
