I'd start with checking here and with manufacturer about support for Server 2019
https://www.windowsservercatalog.com/
also check the manufacturer's site for the latest ROM bios, firmware, chipset and driver support pack. Dump debugging is beyond scope of forums support. For this I'd suggest starting a case with product support.
