I think you need to create a custom install disk using the "image builder" I had done this in the past with 3rd party network cards.
Check this out here:
Basically, you are going take your iso, import it into the image builder, slip in the driver(s), and export your custom iso. Burn the iso and use it to install. I had also used the custom ISO in "update manager" between compatible versions(doesn't seem to be your case right now, but an fyi) to do an upgrade across the country.
