I built a NUC running Windows 11 into a tiny portable server for a project I was building and can confirm it boots and functions just fine without being plugged into a monitor.
I just plug it into a power source and it does what I need it to do, but I can plug a monitor and keyboard (and sometimes a mouse because keyboard-only navigation seems to be getting less and less supported/intuitive...) if I need to perform troubleshooting.
