Intel Desktop PC: Should integrated graphics be disabled from BIOS/UEFI when using a dedicated GPU?

I'm running an MSI Z790 board and the default setting in the UEFI for "IGD Multi-Monitor" ("IGPU Multi-Monitor" on an older system) is Enabled. I have an NVidia card installed, which is set as primary ("Initiate Graphics Adapter" or "Primary Graphics Adapter" set to PEG)

I was wondering what are the pros and cons, if any, of leaving it like this and whether it's better to disable it, if not benefiting of anything? Any impact?
Historically I've disabled the IGD Multi-Monitor feature and ran just fine, but just noticed that the default seems to be for it to be Enabled on my new mobo.

Potential reasons for leaving it ON:
If you specifically want to use Intel QSV (QuickSync) video encoding and/or decoding, otherwise you cannot access the iGPU it seems (from my testing with ffmpeg, OBS Studio)
If you specifically want to connect a monitor to the motherboard's video outputs instead of the dedicated card's, actually using the BIOS "multi-monitor" feature. Don't know exact scenario where you would need that.

One less GPU exposed by the OS to all software: might this lead to better stability in certain scenarios? Are there any known programs which get confused by having 2 GPUs active?
One less driver and potentially service/exe loaded (or is it that some are still loaded even when the iGPU is disabled?)
