Alt+tab on only one ubuntu monitor?

Question

linux

Hello. Tell me, please, how can I make altab work only among programs that are located on the first monitor. That is, I see several options
1) different hotkeys for altab of the list of programs on monitor A and monitor B. I press alt + tab - between the windows of monitor A. I press (another hotkey) between the windows of monitor B
2) altab works only with those programs on monitor that currently has mouse focus. I am on monitor A - I get a list of windows on it. I am on monitor B - I get its list.
3) block certain programs from altab and put them on monitor B. Then I can altab on monitor A and never get focus on them.
Any method will do .
