How to peek inside a bios that comes as a "upd"?

[my03]

Hi all,t
I have a Fujitsu U729 laptop running the latest 2.30 bios (InsydeH20) on this thing and it is abolutely great with one drawback: of the two m.2 slots (one houses a m.2 ssd and one houses a whitelisted Sierra GSM module) i really really, at the end of the day, would like to remove that white-list.
But first things first. I assume this laptop/bios hides a few settings in its bios. 

I went over here: https://www.laptopserviz.bg/forum/showth...BIOS-TOOLS and downloaded a few older tools that supposedly was able to show various things from the bios

Downloading that package brought me a number of different versions of executables (some i could even run on W11). But they all expect bios-files with ".FD" extensions. When i google tools, they all seem to expect bios-files that have the ".bin" extension (or ".rom"). In my case, when i download the official bios and unpack the .exe file to get to its innards, all i find are a couple of ".upd" files (~11mb large each one).

Renaming them to .rom or .bin will not make them load into this insydeh20 editor.

Any hints what i can try next?

All i really want to do at this stage is to peek the menus of this bios.

thx in advance
