I do not think I need to do that at the moment but I definitely appreciate the offer.I'd gladly let you remote into any system I have

My bios mod skills are zero. Just looking at your screenshot I know I could have a lot of fun in there but I have never done any bios mods to my own computers. I will just tell you what I know about that register.
There used to be a rumor that I believe Intel might have started that setting that register to 2048 (2048 / 8 = 256 Amps ) would tell the CPU to ignore this limit. I have never found that to be true. It might be true on some Intel processors but on my 10th Gen, if I set that register to 256 A, I still get lots and lots of EDP throttling when running 10 threads of Prime95 Small FFTs.
On newer CPUs, Intel changed the name of this register from the PP0 Current Limit to Power Limit 4. It is the same register, in the same location with the same layout. Other than the new name, I do not think this register has changed all that much.
For 2nd Gen and newer CPUs, the maximum number this register can hold is 8191. Divide that by 8 and that is equivalent to 1023.875 A. If I use ThrottleStop to set this register to the maximum value (1023) or if I use ThrottleStop to set this register to 0, either way, the EDP OTHER throttling immediately stops. A setting of 0 tells the CPU to ignore this register.
I originally suggested changing this from 0x680 to 0x980 because I thought that would be enough to give you some more headroom before throttling. You might have to go higher to eliminate all EDP throttling or it might be best to set this to 0. If you can remove the PRIMARY_PLANE_CURRENT_CONFIG_CONTROL [LOCK], that would allow you to use ThrottleStop to adjust the PP0 Current Limit. If it is set to 0 and the bios locks it, I do not think you will have to worry about this setting holding you back.
Hopefully you can try a few different settings without creating a brick. I am looking forward to your results.
