Is it possible to split a monitor into multiple virtual monitors?

Question

Monitors

Is it possible to split a widescreen monitor (24x10) into multiple virtual monitors? It’s not easy to make “windows with anchors”, namely, what would be in the center, for example, a game in full screen mode, and along the edges, as if on neighboring monitors, was, for example, a chat or what messenger is open in a “vertical” column?
It is conditional that the center of the monitor be like 16x10, and not "approximately", but clearly tied to the resolution. And the side speakers were separate areas that could not even be touched without switching to them. Plus, for example, if you start a stream, then it would be captured only from the "central monitor"?
Snap Assist allows you to share in windowed mode only.

I have already reviewed three dozen programs.
Creating virtual monitors is not a problem, they will even come with their own taskbars, shortcuts, etc. but you can't limit the area for fullscreen applications. Just as I understood, you can not limit the edge of the virtual display for the mouse. The mouse walks on all displays regardless of anything. The point is in Windows itself. It works on the principle "I see the monitor, I don't see obstacles", and opens the application in full screen.

Maybe I missed something and does anyone have a solution to the problem?
It's just ridiculous that even ultrawide monitors don't have multi-monitor emulation in the hardware. Why are they even needed...
Moreover, even if you have two physical monitors, you cannot switch between them, or expand them (and the mouse flies to the adjacent monitor, and does not cling to the edge of the monitor, in order to get into the browser scrollbar, you need to be a virtuoso, or try to emulate through the same software on different monitors, different unique desktops, choosing such software that would not allow the mouse to move from one desktop to another (in theory, in practice there is nothing to check on). between monitors (count between desktops)
You can also switch between monitors through a virtual machine, but also a crutch solution.

Answer 1

Search result:
Monitors in the current realities for full-screen applications cannot be divided. For windowed applications, you can use the software, the links to which are in the question, or its analogues (many of them).
There are a couple of monitors on the market that at the hardware level allow you to emulate virtual monitors, but without the ability to customize them (set their width).
