I'm trying to install a SSD drive to boot my Optiplex 990 MT system from it.

I want to but the Samsung SSD 970 EVO Plus NVMe M.2 250 GB but I have many concerns and doubts regarding the PCIe slots version and the BIOS compatibility with booting from such storage chip.

Can someone help me with this subject as I'm not good with all these technical details?
