[HELP OR NEEDED SUGGESTIONS] Opencore 0.6.9 High Sierra Nvidia Problem

I am building a Hackintosh for my old PC with Hardware Configuration

CPU Intel Pentium G2020 (Ivy Bridge 3rd Gen) Motherboard ASUS H61M-K GPU GeForce GT 710 2GB & I don't know it applies to this processor Intel HD graphics 2500

RAM 6 GB DDR3 1333 MHz HD WDC 500 GB

I have successfully booted into the apple recovery and downloaded the macOS High Sierra from it to install but in the end it stops at "An error occurred while preparing the installer try running this again". But I know it has to do something with the graphics settings to use DGPU in the device properties of config.plist

Thanks for help in Advanced!
