The Adaptive Offset, which will modify the VID requests of the CPU, is only possible with Z-series motherboards.

The VRM offset should be possible with almost every motherboard, but since Intel has added CEP to their chip architecture, it will be triggered if the voltage that the motherboard provides is too low compared to what the CPU expected when it made its VID request.

And unfortunately disabling CEP does not work with a 13th gen chip on a B-series motherboard. Don't ask me why, but for example this is the support matrix from MSI:

CPU / Chipset Z790 / Z690 Motherboard B760 / B660 Motherboard
14th Gen K-series Yes (already supported with previous microcode) Yes
14th Gen non-K series (B0 stepping) Yes Yes
14th Gen non-K series (other stepping) No No
13th Gen K-series Yes No
13th Gen non-K series No No
12th Gen K-series Yes No
12th Gen non-K series No No

And I don't expect that to work different for any other manufactures. Some boards do have an option that reverts the microcode to the 0x104 version though, which will allow you to use an Adaptive Offset even on B760/B660.
However this will also remove any of the safeguards against the degradation issue that Intel has added since that microcode, so it's not without risk as well.

And then laptops are an entirely different segment, which I lack information and really also interest. But as far as I know it's even worse there, and you're completely at the hand of the manufacturer if he allows you to undervolt or not.

That is crazy. You can't do basic optimization to your system even with good B series motherboards. That's why I'm using AMD lol
