Correct M2 slot for Samsung 870 Evo ?

[Elgato748]

In my MSI MSI MPG Z690 Edge WIFI DDR4 the first M2 slot is PCIe 4 from the CPU. The other three are from the chipset.
In the manual there is this notation:
⚠ Important
∙ Intel® RST only supports PCIe M.2 SSD with UEFI
ROM.
∙ M2_2~4 support Intel® Optane™ Memory.
Do not really understand what this means.
My intent is to install the 970 EVO in m2 Slot 1. Any issues?
Thank You

Just install it in the first M.2 slot. You will be fine.

No issues if that is your primary drive.
