This explains why the Nvidia card won't work. The newest version of Mojave will only output a black screen.
And it's just as I suspected with the trackpad. Looks like the newer Razers Blades took the base model trackpad ELAN hardware.

Follow the instructions, patch a fresh DSDT with this code:
Code:
into_all method code_regex If\s+\([\\]?_OSI\s+\(\"Windows\s2015\"\)\) replace_matched begin If(LOr(_OSI("Darwin"),_OSI("Windows 2015"))) end;
Update the XOSI and see if you as stated in the comment and see if you get anything out of it.
If it doesn't work with doing all that above. Remove the Voodoo2CHID kext and replace it with the one attached and see if there's any changes, keep the changes you did above obviously.
