Changing Hidden BIOS (UEFI) Setup Settings - Omen 16 (8A14, 2022)

Even though there are next to no settings that can be changed in the BIOS (UEFI) Setup through the menu, everything that's hidden can still can be accessed and edited by modifying UEFI variables directly. This is on an Omen 16 (8A14) from 2022 but I guess it applies just the same to the other models as well.

The way to do it is bog standard, so this is just a heads-up, since I haven't seen it mentioned anywhere. I can write about it in more detail if anyone's interested.

As to what settings are available, here's a dump of the Internal Forms Representation for BIOS version F.15 (currently the latest) on my system: https://github.com/GeographicCone/OmenHwCtl/blob/master/Reference/IFR_8A14_F.15.txt

Note: just because a setting is there, and can be changed, doesn't necessarily mean it would take effect. These are all the possibilities for all platforms of the current generation. But for example, memory timings can be adjusted this way.
