a list of am4 motherboards that do support headless pc(booting without gpu)?

I mean I could throw at it a 10€ gpu, but that wouldn't really solve it

the systems doen't really need a video output, and the chasis have no space for a gpu, apus are not alright

Maybe this article, at Distributed Computing Adventures - Distributed Computing, Volunteer Computing, World Community Grid & more, can help you: Which AM4 mainboards boot headless without GPU?

I think the majority of Asrock pro boards can work headlessly

As far as I know this is done by a software, tightvnc was great prior windows 10 1803, if you want headless then install windows 10 1709. Microsoft I think blocked that feature because to this day tight vnc does not do that anymore on newer windows 10 version after 1709. You can always use microsoft software but is not as good.

Intel Pro products usually boot since start I mean the bios, vnc only works after windows started.

That's the issue I don't think many Ryzen motherboards will even post without some sort of igpu or dgpu, intel is very different because the majority of chips have imbedded igpu whether you want one or not. I think the Asrock b350 pro would work headless and the Asus x370 prime would but I'm not sure about others.

This is all information I got with very little experience when I was once asked to make a remote access control for some Off-site cnc so any rubbish I quote needs to be double and triple checked.
