[REQUEST] XPS 8930 enabling hidden options (4gb Decoding and fast boot)

My bios version is XPS1.1.12
My biosreg.bin is
biosreg - Copy.zip (3.7 MB)

So used a AMIBCP on my bios and found so much settings in it that I want to be shown/enabled on my bios. I don’t know what exactly I should do to achieve this. I did check HWINFO and it does say I have Guard Boot. Because I have guard boot does that mean I cant mod the bios? Or do I have to use some other method.
