11th Gen Tigerlake Undervolt (Bypass Plundervolt prevention)?

Just saw this article.

Looks like someone was able to bypass Plundervolt mitigation issues with undervolting which we thought were fused on-die.

I’ll try to see if this is feasible on Linux sometime this week after my physics competition. Let me know if any of you give this a shot!

Edit: the comments don’t look exceedingly positive, but I’ll give it a shot anyways. Who knows!
