I mean a some sort of a splitter driving two monitors. From reading replies and doing a bit of research, It looks like DisplayPort has the feature of carrying several video streams and supports that kind of splitting but not HDMI; Even HDMI 2.0 seems to have the capability of carrying 2 channels per physical port it's bandwidth is limited to 18Gbps whereas DP bandwidth is 32Gbps.
Yes DisplayPort MST hubs exist such as: https://www.tripplite.com/2-port-displayport-1.2-dvi-multi-stream-transport-... Even tripple adapters: https://www.startech.com/ca/AV/Displayport-Converters/Triple-Head-DisplayPor... I suspect that one needs active adapters to convert DP to VGA/DVI/HDMI, while a single DP+ port on the motherboard can use passive adapters instead. Most boards seem to have DP+ ports these days, although I am sure exceptions exist.
I just need HDMI to DVI converters for some rather old 1080p monitors that are still working perfectly fine.
Yes those are simple at least.
The board Asrock AB350 mini ITX, or more precisely Ryzen 2400G supports HDMI 2.0, so in this configuration it should be possible to drive two 4K screens at 60Hz.

I wonder if it's possible to connect more than two screens with two HDMI ports? (This question is more theoretical than anything else).
Lennart mentioned MSI B350I ITX motherboard that has DP and HDMI. I looked at it for a bit, compared to ASRock the following put it at disadvantage:
* It's not yet available in stores * Ethernet chip is not Intel * Reviews show that MSI BIOS is consistently worse then any other boards * Really obnoxious naming (They even managed to call something more obnoxious than fatal1ty)
Yeah it would not be my preference either. Seems the ITX board selection for AMD is rather crappy so far. Quite a few choices with better ports for intel it seems. -- Len Sorensen
