How to artificially set the borders of the working area of ​​the screen?

Question

Windows

Hello!

Experimenting with the appearance of the operating system, just from a research point of view.
I have Windows 10, I'm currently playing around and giving the system a look similar to MacOS, in the process of converting the appearance of the system, the question arose, how can I artificially limit the edges of the desktop?
Let me explain what I mean. When you expand a window to full screen, it takes all the free area of ​​the screen, except for the taskbar, wherever the taskbar is located, it creates a border for the window, the question is, is it possible to somehow create the same border, but without participation the taskbar itself?
Instead of the Windows 10 taskbar, I use the Nexus dock bar, it creates its own border for windows, using the Rainmeter application, I made a panel at the top of the screen that resembles a Mac, but now I need this panel to also be a border for windows, like the dock bar at the bottom of the screen.

Thank you in advance for your help!

PS I know that you can make your own application, which will have the functionality I need, but I don’t have the necessary skills for this, and for sure someone has already done something similar, so why reinvent the wheel.

There is an actual window manager application, in it, emnip, you can create a rule that determines the size and position of any windows.
At the start of the program - exactly. Is it possible to set the rule "always" - I don't know, you can set and experiment if you want strange
