Black screen on Installer boot with NV GPU

I always get a black screen (monitor shuts off) after the initial text phase where i think it tries to boot the graphical installer. I think this is because it wants to switch back to the iGPU and disables the Nvidia GPU.

I have gone through the WhateverGreen Shiki and Geforce FAQ without success. (It tells me to rename GFX0 to IGPU but how do i do this?)

I‘m using BigSur with shikigva set to 40 and the iMac15,1 SMBios.

My CPU is an Ivy Bridge 3470 and my GPU a Geforce 730 GK208 on a Intel series 7 motherboard from HP. Am i doing something wrong?
