I had a similar video issue when I was running a pair of Debian web servers and didn't want a monitor permanently connected - I was using VNC software to maintain them.
At that stage it was a VGA rather than HDMI form but it was easy enough to dummy up a couple of DB9 plugs with some resistors soldered to the relevant pins. I still have those 'dummies' somewhere but can't put my hands on them at the moment to get the resistor values or pin placement.
If you already have an unused HDMI -> VGA adapter cable, you might be able to do something similar at DB9 pinout level. It would be a shame to go to Win10/11 for that sort of project !
I will search harder if you cannot find dummy VGA plug info elsewhere.
