// -1 unknown, 0, disabled, 1 enabledINTN GetSecureBootStatus(){
EFI_STATUS Status; UINT8 SecureBootMode; UINTN BufferSize
= sizeof (UINT8); Status = gRT->GetVariable (
EFI_SECURE_BOOT_MODE_NAME ,
&gEfiGlobalVariableGuid, NULL,
&BufferSize, &SecureBootMode
); if(EFI_ERROR (Status)) return -1; if(SecureBootMode

You use the GetVariable() function from runtime services. The name of the
variable is SecureBoot and the guid is EFI_GLOBAL_VARIABLE. Refer to UEFI spec
section 3.2
