I use Armoury on my ASUS motherboard and download the ASUS recommended drivers. Windows handles everything else unless there is a specific driver for them (nvidia graphics in my case).
You could go without Armoury of course.
Don’t think I have intel assistant installed. Just using whatever windows or asus provide for the iGPU. I do have my iGPU active but I don’t use it for video display since I have the nvidia card (I use it for other things, but not display).
