Render games on dGPU?

[sunryze]

So I have a RX 5700 XT and UHD 630. I patched my UHD 630 drivers and they work on Windows 7 without any test mode. But my problem is that AMD poorly codes the Windows 7 drivers. I get microstuttering with aero enabled, fading is nonexistant too. The Intel card though runs a lot better. So I was wondering if I can run my displays off of my UHD 630 for the better coded desktop experience, but render my games on my dGPU for better performance. 

Im using Windows 7 Professional SP1 fully updated to 2020-12, excluding telemetry updates.
