I'm in the same boat, same board and all 3 of my m.2 slots are occupied and besides you'll never perceive the difference anyhow in most cases with x8 vs x16, doesn't even come close to saturating all the bandwidth. Through testing, I've not seen any differences worth mentioning in 3DMark benchies with one in m.2_1 or not. I will say, I didn't buy a 1k mobo to not eventually run a Gen 5 SSD in slot 1, you'd want your fastest SSDs in those slots (off CPU) and all else off the PCH.
So just to be clear (as I'm building a 12900k build out on my maximus extreme z690 as we speak), if I use a gen4 M2 nvme on m2_1 slot, it should still allow me to have 16x on my PCIE5_1 slot, correct?
It will only impact it if I use a gen5 M2 nvme in that m2_1 slot, right?
I see the warning the m2_1 slot shares pcie5 bandwidth with pcie5_1 & 2 slots, but if I'm using a gen4 M2 nvme in that slot, it should not have my lanes on pcie5_1 slot for my gpu?

Would be nice if Asus included a detailed explanation of how the M.2 Drives share lanes with the PCI-E GPU Slots.....something more detailed within the manuals.
I would like to see the benchmark comparisons of x16 vs x8, as I have read (not tried it) that the 3080Ti / 3090 are in that category of GPU's now saturating the x8 lanes......

this may be true with PCIE3 x8 or x16 but not even close on PCIE4 or even less so on 5. I'll try and get some results up soon, PM me rj if you like, I'll work with you on this.
