Sounds good! Thanks! Will hold for at least this week. Still need some more RBs.

Hi Bret,
The V7 version is OK from my side. Reviewed-by: Dandan Bi <dandan.bi at intel.com>
Please hold to see if any comments from other reviewers.
Hi Jiewen and Jian,
Do you have any comments?
Thanks,
Dandan

> The 14 patches in this series add the VariablePolicy feature to the core,
> deprecate Edk2VarLock (while adding a compatibility layer to reduce code
