Make KDE Plasma Task switcher show only on primary display

Is there a way to get the task-switcher to only display itself on the primary monitor.

After reading a similar question and the response from a KWin maintainer I think we can safely say it is not possible (even though the question was not precissely the same).

Yes alt+tab is part of KWin (called TabBox there). The only way to extend it would be from within kwin project. But that's not an easy task to be totally honest. The code is designed for only one view, changing that is something I would say is close to impossible due to the way how the tabbox is "special". E.g. it intercepts key events, evaluates them and then forwards them to the view. If there are multiple views, who knows what will happen?
