Macrium PE/AOMEI PE - intel HD4000 graphics not working

[L V Gandhi]

I tried both Macrium reflect and AOMEI for backup and PE building. In both softwares PE built shows minimum resoltion of 800x600. It does not take into the installed Graphics adapter Intel graphics HD4000. Is there any way during PE building, the drivers for intel HD4000 can be included in the PE?

I am not very good at these things.
I saw in building winpes. There I saw importing drivers in mount. But they ask for .inf files. I see only exe files fro drivers from intel for HD4000.

If given, step by step instructions will be helpful, please.

Again after doing some search, I found method to install drivers while making iso.
dism /add-driver /image:"pathto m ount folder" /driver:"\PathToDriver\drivername.inf"
This did not help.
However while running, if I do
drvload "\PathToDriver\drivername.inf"
It works.
However as for as macrium boot disk, I copied graphics driver folder as sub folder to drivers folder. While booting graphics driver installed and screen resolution is OK.
I would like to add a browser and partition guru program to the boot disk.
Further the wireless driver for intel dual band ac7260 does not have an .inf file. How to add driver for this wifi to the boot disk.
How to do that. Any solution will be appreciated.
