So, we can say that I can install two M.2 SATA SSDs on my M.2 NVMe SSD slots ... How to know if your M.2 NVMe slot supports the M.2 SATA SSD?

i know it may see silly , but still i need to know whether msi b450m pro-vdh max support nvme ssd . i think it do support , but when i go to the bios setting it only shows option to AHCI/RAID , no NVMe option (i am not installed the nvme yet ).
