**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**

Jiewen:
  This patch is only for UEFI spec mantis 1908 change in SecureBootConfigDxe.
  This spec change just ask some drivers do some modification, it does not ask the HII core to be modified, so this spec change will not cause compatibility issue.

  For this patch, it only touch the UI setting, did not touch the modification of pk, kek, db, dbx, dbt EFI variable.
  I did the following unit test in EmulatorPkg WinHost.exe and Intel AlderLake RVP:
  1. In PK Options, Enroll PK, check the "Attempt Secure Boot" is not gray and enabled.
  2. In RVP, Set "Attempt Secure Boot" to enable and disable, check it does work, and device can boot to Windows.
  3. In PK Options, delete PK, check the "Attempt Secure Boot" is gray and disabled.
  4. In DBX Options, Enroll Signature, check it does work, and the "Delete All Signature List" is not gray.
  5. In DBX Options, Delete all signature, check it does work, and the "Delete All Signature List" is gray after all signatures are deleted.
  6. In KEK Options, Enroll KEK, check it does work.
  7. In KEK Options, Delete KEK, check it does work.
  8. In DB Options, Enroll Signature, check it does work.
  9. In DB Options, Delete Signature, check it does work.
  10. In DBT Options, Enroll Signature, check it does work.
  11. In DBT Options, Delete Signature, check it does work.

  @Pingle, Sneha S Would you like to help to verify the secure boot functions again in another Intel RVP?
  @Felix Polyudov Would you like to help to verify this patch with AMI browser? Since AMI submitted this UEFI spec change, if verify pass, would you like to add a "Reviewed-by' for this patch?
  @Bi, Dandan is HII expert and the reviewer of edk2 HII and UI modules, would you like to review this patch? And add a "Reviewed-by" for this patch?


  And I create a PR for this patch: https://github.com/tianocore/edk2/pull/5411, all CI checking are passed.

  Thank you.
  Tan Ming.

Thanks for the update.

First, would you please clarify which test you have done for this patch set.
Have you tested all previous function to ensure it still works?

Second, would you please clarify if there is any compatibility issue to follow the new UEFI 2.10?
For example, what if the core HII is still UEFI 2.9? would that still work?

Third, because I am not HII expert, I would like to have HII expert to comment the HII/Browser related change.

Thank you
Yao, Jiewen
