Hello @Leomm try to use ''NV Clean Install'' - you will find it if you google it. That is a helpful program that mods the drivers and it installs them for you, no hussel with inf modding. Please use that and tell me what happened.
Normally, due to your GPU vbios, as I can see - according to the subsystem id - the drivers should work Plug&Play. What bios is your system running?
Hope it helps.
And for the throttling problem -- go to bios -- activate the IGPU-- save -- login to windows -- restart-- deactivate igpu and set to peg -- and also always peg on -- if your are running the (A11 unlocked bios) save and reboot.
If all of that will not work then the vbios might be corrupted, i will give you a different one if you want maybe that will work.
Best Regards.
