How to disable Intel CPU based HD Graphics 4600 Completely?

[MP7]

Hi All

We have assembled PC (ASUS Z97 Pro Desktop Motherboard with Intel i7 4790 Processor )

The CPU ships with Intel HD Graphics 4600 integrated processor graphics

I also have NVIDIA GTX 750 discrete Graphics card

Now I wanted to use only NVIDIA GPU and waned to disable Intel HD graphics completely right from BIOS and device drivers etc.

However unfortunately I don't see any options to disable Intel HD graphics from BIOS

Is there any way out to disable Intel HD graphics ?

Also if this is possible, are there any implications?

My purpose of this PC is solely lab virtualization with Hyper-V / VMware. If I can't disable this graphics, this will put more load on CPU specially when I run multiple virtual machines

Any insights are highly appreciated.

Thanks

Mahesh

Try to uninstall its driver(not recommended) from device manager.

Normally when you connect VGA/HDMI etc cable to the graphic card, the PC will not use the integrated graphic.
