Gen 4 NVMe New windows install advice please

[Reedweaver]

I dont have an 11th gen CPU yet (M.2 Slot 1 disabled) , what happens when I install Windows 10 using M.2 Slot_2 and then when I get the 11th gen cpu, move the gen4 SSD to M.2_Slot_1?

I have a Asus Z590-P Wifi motherboard that I am building a system with.

^^That^^ plus i thought it didn't matter if you plugged a gen 3 drive into a gen 4 slot as it's backward compatible.

My motherboard doesnt recognise the SSD in the M.2_slot_1. Looking at the motherboard manual it says:

"Intel® 11th Gen Processors M.2_1 slot (Key M), type 2242/2260/2280/22110 - Only Intel® 11th Gen processors support PCIe 4.0 x4 mode, this slot will be disabled for other CPUs"
