How to set my dGPU as primary/ disable the iGPU

Laptop : Acer Nitro 5, AN515-42

CPU : Ryzen 5 2500U

GPUs : Radeon Vega 8,

             Radeon RX 560X

OS : Windows 10 Pro 64 bit/ Debian sid

Radeon Software : Adrenalin, 18.12.2

BIOS Version : 1.11 (latest as of Jan 2018)

RAM : 8GB DDR4, 2666Mhz


I want to make my dGPU the primary display adapter in my laptop.

I have already tried disabling the Vega 8, but no option is present for this in the BIOS.

I then tried disabling the Vega 8 from Device Manager. However, it simply switches to Microsoft basic VGA adapter  and doesn't use the RX 560X ( though that can be viewed in Radeon settings).


I need to disable my iGPU, or set the dGPU as primary in order to use RoCm, as it works only with a single GPU setups.


Any help would be really appreciated. !
