V/F Points Missing

I was trying to follow the Valour549 Ultimate Throttlestop Guide, and there, he sets V/F Point 1 to the same value as their CPU undervolt, and the other points to 0 (?) to achieve extra stability at lower loads as shown below.

However, when I open the same menu, it looks like this instead:

The V/F points MHz values are missing and I cannot click to edit them, which is also the case for the mV values which I cannot directly control, however they seem to be following my CPU Core/Cache undervolt. I have an i7-11800H laptop CPU, and saw online that V/F points were introduced with the Comet Lake Architecture (10th Gen), maybe mine supports it but the laptop manufacturers didn't bother implementing them?
On my laptops BIOS settings, I've found these options that seem to be related.

I wonder if the VF Point offset's here are supposed to correspond to those MHz values, since they're all 0 on both my BIOS and ThrottleStop. If that's the case, could I plug 800 MHz to the VF Point 1, possibly leave the rest empty and call it a day? Would I have to/Would it be possible to find the MHz values of the other points for my CPU?
These VF Point offsets might be the current offset too, so I'm hesitant to touch them.

Valour549 Ultimate ThrottleStop Guide
That is a good guide but it was written using his fully unlocked 14900HX processor. Your 11800H does not appear to support V/F Point tuning so do not try and use that ThrottleStop feature.

Intel first added this feature to their fully unlocked 10th Gen Comet Lake K series CPUs. Here is a V/F example from my 10850K.

ThrottleStop is able to read the MHz values from the CPU. The 10th Gen used 8 unique V/F points. The 12th Gen and newer use up to 11 V/F points but not all of these points beyond the first 8 are unique. Your screenshot above from the Valour549 Guide shows that V/F Point 8 through 11 are all at the same MHz.

Without access to any Intel V/F Point documentation and without access to a wide variety of hardware, I left this ThrottleStop feature unlocked so users with different hardware could experiment. My best guess is that none of the H series CPUs support the V/F Point tuning feature. Your screenshot shows that for 11th Gen H, this feature does seem to exist. It is likely that Intel thought about adding this feature but later decided to disable this with a microcode update for all of the retail H series processors.

I would not try to use V/F Point tuning on an 11800H. In the future I might disable this feature when the CPU returns a value of 0 MHz for each V/F point. That seems to be a clear indicator that this does not work.
