Hi, please see here: Dell EMC PowerEdge™ / Microsoft Windows Server® OS Support (LTSC) [URL]   It looks like what you want is not supported, I'm afraid. Hope this helps.
Anyone had any luck installing Server 2019 on a PowerEdge T310? The specs say that only Server 2012 R2 and below are compatible but I only have a genuine copy of Server 2019. I also have 2008 R2 but it is getting a bit long in the tooth and is now unsupported. It should install OK but it is driver & software support that I am concerned about.
