I believe the ARM platforms already have the change. At least the ArmVirt does and some of the edk2-platforms.
This is not news. It’s been broadcast repeatedly for the last 3 months. And the last 6 months. And the last 15 months.

Include Leif. This change adds new library class dependency for the variable driver. So, it requires to update the platform DSC file. It will impact ARM platforms.
Thanks

Still waiting on some R-bs.
Have a new doc that will make it into a v7, if it helps anyone with their review…

Subject: [EXTERNAL] [edk2-devel] [PATCH v6 00/14] Add the VariablePolicy feature
REF:https://nam06.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D2522&data=02%7C01%7Cbret.barkelew%40microsoft.com%7Cdf2ee1dbc25a4810f5ce08d817674112%7C72f988bf86f141af91ab2d7cd011db47%7C1%7C0%7C637285079522114249&sdata=1%2F3MkPm5HuXeG%2FEaQgl%2F%2F8Tqu3UvgDs6Ich2ezXgjuY%3D&reserved=0
The 14 patches in this series add the VariablePolicy feature to the core,
deprecate Edk2VarLock (while adding a compatibility layer to reduce code
churn), and integrate the VariablePolicy libraries and protocols into
Variable Services.
Since the integration requires multiple changes, including adding libraries,
a protocol, an SMI communication handler, and VariableServices integration,
the patches are broken up by individual library additions and then a final
integration. Security-sensitive changes like bypassing Authenticated
Variable enforcement are also broken out into individual patches so that
attention can be called directly to them.
Platform porting instructions are described in this wiki entry:

Discussion of the feature can be found in multiple places throughout
the last year on the RFC channel, staging branches, and in devel.
Most recently, this subject was discussed in this thread:
