Actually, motherboards do not include integrated graphics, it's all in the CPU/APU. The mobo you linked would not provide graphics either.
AMD unfortunately does not have a high end APU released to consumers right now (there are some 4000 series, but only to OEMs I believe). However, for a HomeLab setup, you might find a cheap GPU to be useful for many things (including hardware video transcoding).
Its motherboard dependent but its definitely something to check with AMD Ryzen motherboards.
Even hardware that is made to be run headless ("server-class") is hopelessly broken. They give you a proprietary graphical console that isn't even just a VNC server but has to be accessed with a web browser. And, if the server is more than a few years old, some deprecated, unsupported plugin like Java or .NET will be required. I have an old Dell R710 whose remote console I will never be able to access, because it only works with Java 6 (or so I'm told, I'm certainly never trying that; I wouldn't even know where to begin to try to set that shit up.)
