I h i9-9940x. can i use m.2_1 and m.2_3? if it is possible, can anyone show me how to set the bios for this setup? thanks in advance.

yes, the cpu can support, however, the bios setup is motherboard dependent.

Is one of the m.2 ports favored over the other. it will be used an m.2 ssd. thanks

I have used the one further from the CPU for a Samsung Pro 1TB NVME SSD, and I'm getting full speed.

Can you run an i9980xe on this board stock and can it handle overclocking?

The board can definitely handle over locking. As to that specific processor, look up the motherboard on the ASUS web site. Under its support tab there is a complete list of compatible processors as well as ram modules.
