Are any m.2 slots sharing PCIe lanes? How do I determine this?

The product information does not specify whether any M.2 slots are sharing PCIe lanes. To determine this, you should refer to the detailed motherboard manual or the ASUS support website.

Does this board run SLI?

Yes but no. You won't fit anything bigger than two 2080's. The bottom x16 slots also run in x4 mode.

Can I get this to run DDR5?

This version is DDR4 only, hence the D4 in the title. The non-D4 is DDR5.

Does the Z790 chipset support populating all 4 slot on a DDR4 version MB?

Yes, the Z790 chipset supports populating all 4 slots on a DDR4 version motherboard.

what is the fastest RAM speed you can get with gear 1?

The fastest RAM speed you can get with gear 1 is 3600 MHz.
