You would need to do this from the BIOS. You would gain access to the BIOS during the first boot screen prior to Windows. It will either be "F12" or the "del" key most likely.
Once there, you'll most likely be looking fo something related to Integrated Peripherals and specifically onboard video adapter. You'd want to select some sort of disable option for this.
