display – Is it possible to “emulate” virtual monitors like Windows does for remote desktop users?

I want to remote desktop into macOS, but when I use a client like VNC Viewer on my Windows PC, it only allows me to go up to whatever resolution the macOS machine has (like 2560×1440 on an iMac).

My Windows setup has 3 monitors attached (4K, 2.5K, and 2K). If I use native Windows remote desktop into a tiny laptop with a 1920×1080 monitor, the program still opens up in fullscreen. It basically emulates having 3 monitors connected to the laptop.

I want the same but for macOS. What options do I have in that regard? Bonus points if it can run headless, so I can use it on a Mac Mini or a Mac Pro stashed away in a closet somewhere.
