RAID-1 with SSD

Hi,
I have two dedicated servers, one with HDD and the same server with SSD. I want to install manually, without OVH template. When I boot into BIOS and more or less (the procedure is out dated with the correct BIOS options) follow this procedure: https://support.us.ovhcloud.com/hc/en-us/articles/360004809700-How-to-Configure-RAID-from-the-BIOS
I get a prompt for the raid configuration utility for the HDD server, but the same procedure doesn't seems to work for the server with SSD. What is actually wrong here? Is this not supported? It is a Windows based server. The setup obviously sees two separate SSD disks.
