Extract drivers from the machine:
Export-WindowsDriver -Online -Destination c:\Drivers
Zip these into an archive (such as Drivers.zip) and upload these into a file copy module.
On your image, create an image profile and enable the file copy module you created.
On your setupcomplete.cmd file you will need:
pnputil.exe /add-driver c:\drivers\*inf /subdirs /install
You may need to recapture your image with this setting. Now all you do for new models is extract drivers, create a file copy module and a new image profile.
