Via hdmi: it depends on your monitor - most of the time no. Some 4k monitors got this feature tho.
Via browser: sure just open both webinterfaces in different windows.
If you got trouble to load them with http://octopi.local just use the ip of each pi instead.
Another option would be to use something like this
You can get a physical hdmi splitter with a scan feature. It will switch between each screen in a cycle till you stop it. Don’t remember seeing one with picture in picture but they might exist, good place to look is CCTV resellers.
