Multiple monitors setup: Is it possible to trigger grid view only inside the monitor under the mouse cursor?

Everything is pretty much explained in the title.
Basically when I trigger TotalSpaces2 grid view, I want it to be triggered only on my monitor where my mouse above of.

I am reading other threads and I beleive the “sync grids” option should allow me to to that.

I feel I should point out my second monitor is actually an iPad Pro running Duet. Could that be the source of the problem? Wether I check or uncheck “sync grids” the behaviour remains the same: both screens show the grid view…

Can you help me solve that problem?

Sorry, there isn’t any way to show the grid on only one monitor (unless “displays have separate spaces” is turned off in Mission Control prefs, in which case the grid would naturally be on one screen only)
