Modify bios to shield discrete graphics

My notebook is ASUS FX80GE (FX504GE). My notebook is not well cooled. I want to shield the discrete graphics card by modifying the bios file, leaving only the core graphics card. Ask the gods to help!
I uploaded the bios file downloaded from the official website and extracted Section_PE32_image_Setup_Setup IFR.txt
