BLACK LIST. Adjustable voltage control/turbo ratio limits are locked out due latest Win Update/Bios

I have 15 inch Omen from 2018 with i7-8750 and undervolting is broken: latest BIOS no go, I went back to BIOS from 2018, I reset the BIOS and I deleted mcupdateintel.dll and still underolting not working. Any other suggestions? Because I'm getting really pissed. I can see microcode is changed to old and it should work, but it doesn't, damn stupid intel and hp.
BTW I hope you guys don't get fooled: on my system only CPU core doesn't work, all other voltage adjustments work fine, including cache and even HWinfo shows offset for core voltage set, except it doesn't sets and even if I set offset to -1 volt computer doesn't crash

 

Pls add to the list:
Dell Precision 7730 - bios 1.13.1 implements CVE-2019-11157

 

Please add Lenovo Yoga 730-15IWL to the list.
The latest BIOS update (version 2.07) has locked CPU voltage control. I cannot return the previous version of BIOS, because Lenovo does not publish archived versions of BIOS on the website for my laptop model.

 

I'm sure it's been discussed but at a very less than desirable method, Asus has implemented an option to undervolt to a max of -80mv in the BIOS of some of their newer ROG laptops, such as my current Asus GU502L.. It's still infuriating because it's just as stable as stock with -80mv and I know there's more I can squeeze out of this i7-10785H to further lower temps and there's no other way to do it.

However, I plan to see if I can dump the BIOS and edit it and find out if there's a way to unlock the BIOS further by disabling SGX or something and or just opening up the undervolt options all together. May be fruitless and I may end up bricking the machine with a re-flash but i'll be damned and determined.

I'm still a fanboy of Intel laptops because of Undervolting all together since there's no easy way or reliable way to undervolt or control TDP with Ryzen stuff on mobile so there's that.
