I would think as an "IT admin" you could be a bit more specific as to what you're talking about, because frankly it sounds like nonsense. I've seen the HP Microservers discussed here over the years so if there was some huge problem surely there would be a lot of threads on them (I rarely see any). Frankly, they are just an Intel servers.. so I can't imagine there being major issues so long as the devices support Debian 10 as a whole.
Do the Gen 10's have a problem with Debian 10? (probably not given it is one of the most widely used server OS's there is)... so I think whatever you're reading unless you can be more specific, is probably poppycock.

I was just evaluating the hardware in question and asking for opinions
