This system uses software-controlled hybrid graphics - there is no hardware control built into the system board. It must be disabled though the control panel in the driver software.
I doubt it -- it likely is possible on a system that has a true hardware-controlled switching video system, but that's not what you have -- you have a muxless, software-controlled hybrid system.
This doesn't solve my problem. What I´m actually are trying to do is to use my external graphic card (eGPU) to work together with the integrated graphic card (iGPU) with the help of optimus. At the moment only my iGPU and dGPU is using optimus. Thats why i wanted to disable my dGPU. Any possibility to select wich cards are used by optimus?

It cannot be disabled at the hardware level -- use the Optimus or Catalyst (nVidia or AMD) control panel to turn it off.

There has to be a way to disable it at hardware level. Modifying BIOS or UEFI. I need it to be disabled before booting Windows.
