Windows – Installing OS on NVMe based PCIe SSD

I bought an Intel SSD 750 series 400GB disc and I want to install OS onto it. It's nicely plugged-in.

When I try to install Windows 7 x64 onto this drive, first I need to specify a driver that has been attached on a CD with this drive because it is not visible without it. So after the drive is visible it says I cannot install OS there, because:

Windows cannot be installed to this disk. This computer's hardware
may not support booting to this disk. Ensure the disk's controller is
enabled in the computer's BIOS menu.

I've read that I should enable AHCI mode inside BIOS and set the priority of this SSD onto the first place, but the problem persists.

What may be wrong? My motherboard: P6T7 WS SuperComputer

I've been reading more about the problem on the internet and I found out that my motherboard's chipset (x58) does not have NVMe boot mode support. Does it makes this motherboard too old to boot from this SSD? Is there any way I could just bypass NVMe mode and use AHCI instead f.e.?
