Question MSI X570 Unify M.2_3 slot SSD not showing up in bios

[sandwish]

Hi, I have the X570 Unify

Setup as follow:
3700x
2070S
1 x pci-e 4 2080 m.2 ssd on the M.2_1
1 x pci-e 4 2080 m.2 ssd on the M.2_3 (I skipped a slot cause I thought it would cool better)

the bios only detects the first SSD but not the second,

1. Am I out of lanes?
2. Should I move the 2nd SSD to M.2_2 slot?
3. Is this fixable in the bios?

Sorry if these are dumb questions

I tried the 2nd and 3rd slots, neither work. Wonder if I should return it as defect or it's something else
