Attempt to enable SMU Common Options on GPD Win 4

BIOS/UEFI Modding BIOS Modding Guides and Problems

I have an ifr extract as follows:

VarStore Guid: 3A997502-647A-4C82-998E-52EF9486A247, VarStoreId: 0x5000, Size: 0x6BD, Name: "AmdSetup"
...
SuppressIf 
    EqIdVal QuestionId: 0x9, Value: 0xFF
        Not 
    End 
    Ref Prompt: "SMU Common Options", Help: "SMU Common Options", QuestionFlags: 0x0, QuestionId: 0x6, VarStoreId: 0x0, VarStoreInfo: 0xFFFF, FormId: 0x7006
End

I assumed that the QuestionId: 0x9 correspondents to the address in the VarStore and if i set the value of address 0x9 of the var store 3A997502-647A-4C82-998E-52EF9486A247 to 0xFF that the option would appear. This is not the case.

Is there a Mapping table of QuestionId to addresses?
What am i missing?

Look for QuestionId: 0x9 on the bottom. Under the Disable If.

This is the file I’ve got. I cant seem to find QuestionId 0x9 under any disableIf.

There’s no mapping for the QuestionId: 9 under the Disable If. I made the wrong assumption.

But I found this instead.
