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