Disable Plundervolt on Surface Book 3 (i7 1065G7)

I think there is no old BIOS for this Laptop, where plundervolt was not enabled, because it released after that plundervolt became a thing. So therefore i thought, maybe it is possible to mod one of the available BIOS and then flash one of these.

So, is it possible to disable plundervolt with a BIOS Mod ?

There are the firmware-version, which are available: https://www.microsoft.com/en-US/download/details.aspx?id=101315

Is there any chance to get undervolting enabled ? For sure i tried already throttle stop and XTU.

If there is any chance, is there anyone who would help me to find, what i would have to mod ?

Edit: im using Win 11 22H2 Build 22621.1992
