Operating System: Microsoft Windows 10 (64-bit)

As my subject states I’m wondering how to disable kernel dma protection on my windows 10 prebuilt hp omen desktop. I’m aware it’s normally a setting in bios but this very minimalistic bios has no such option that I could fine and I tried disabling it through gpedit.msc and changed the registry from 1 to 0 but in system information kernel DMA protection is still on and I need this off no matter the cost.

You might try disabling virtualization in BIOS.  According to Microsoft quote:

 

Kernel DMA Protection is only supported on 64-bit IA processors with virtualization extensions, including Intel VT-X and AMD-v.
