Strix G531GU BIOS 309 - Undervolt locked?

[Nemesies]

Hello, today i updated my bios to the newest BIOS and the newest Windows Update (Version 2004 OS build 19041.329), and I realised my undervolt on CPU core, cache and IGPU is not applying anymore.

I used the BIOS version 305 before, and the undervolt worked well with ThrottleStop or Intel XTU.

Any ideea what can I do to be able to undervolt the laptop again? (Downgrading BIOS doesn't seem a good option)

Thank you.

I am having the same problem on my GU502GV. I cant change the voltages using Throttlestop or XTU.
How can i downgrade my BIOS to an older version, like 307,

Thanks
