Do you know something about VRMs and Bios cross-flashing? Can you lend me a hand?

I want to increase the power limit on my new GPU (Gigabyte Windforce OC 4070 Ti Super). My card seems to overclock well, while staying at low temperatures on core and vram (sadly no vrm sensors). MSI Afterburner shows power as the limiting factor in a bunch of different benchmarks (all that I tested). JayzTwoCents has a video regarding the power limit of this card, too. It feels bad having a card with low temps and decent overclockability, while not being able to gain the real benefit because of this artificial power limit.

The problem is, AFAIK there is no way of increasing the power limit, except flashing a new BIOS. No modded BIOS exists for my card and there is currently no way to edit BIOS, thanks to Nvidias HMAC BS. But there is still one glimmer of hope. I could cross-flash a BIOS from another model with higher power limit. But this is very risky and I am not knowledgeable enough for this yet. So, you gotta help me out please!

This is my card under the hood:

Which one of these BIOS has the best chance of a successful flash to my card? Which VRMs seem like the best fit?

I appreciate you taking your time for this, this is not taken for granted.

Different card but same problem and the principle is the same, minimal gains from increasing the power limit.

Benchmark Scores I dont have time for that.
The gigabyte gaming OC is the same layout and it looks like the closest match.

Modern GPU's are not like older ones. You can't overclock by 20-30% with a higher powerlimit, you might go from 5 to 8% while loosing warranty, for no reason at all for gaming. I can't help you, nor do i recommend you do it.
