Warning
The Advanced BIOS menu can brick your system, use at your own risk If you choose to ignore the warnings and brick your machine, it is your responsibility not mine.
The files in here are precisely what got me into Advanced BIOS when booting from a usb containing these files on it specifically (which I just copy-pasted from my Linux environment, should work that way from Windows as well).
Some files may be redundant or unnecessary, but this produced the advanced BIOS menu in the UEFI exactly as intended and without doubling the "Advanced" menu item in "More Settings" or rendering an unusable UI as other SREP configurations/bundles did. If you know that some elements contained here are suboptimal or unnecessary, feel free to submit pull requests or even just drop an issue informing me of such and I will happily modify the files and build the resulting image accordingly.
Note
Your system must have secure boot (and trusted platform) turned off in BIOS order to boot from an ISO
For a bootable ISO you can burn in whatever way you do that (I use Linux and am competent with the terminal so I use dd if=/dev/sdX of=/path/to/iso.iso to burn ISOs to flashdrives, try balena-etcher or rufus if you are not comfortable with such) check the releases

If these settings work on your model, drop an issue so I can add them to the README for others with your model to know they worked (or didn't work). Working through your debugging process or even relaying what experiences you have with undervolting using Advanced BIOS vis-a-vis SREP here is also welcome and will likely be extremely useful to others running into issues in the future so feel free to fill the issues up with anything related to this process so the community can benefit... and so can you if you are like me and would otherwise forget.
