is it possible to change the default window manager in kde plasma to bspwm if so how
Offline
I assume you mean you want to run KDE but using bspwm as your window manager instead of KDE'w own window manager (kwin). If so, yes, there is a way. You can follow here:
https://github.com/heckelson/i3-and-kde-plasma
The example above is for i3, but you can choose any window manager.
The main idea is to create a new .desktop file inside /usr/share/xsessions/ that contains: Exec=env KDEWM=/usr/bin/bspwm /usr/bin/startplasma-x11
You might need to add a few things in your bspwm config as well.

Just so that we are clear: You want to replace the window manager inside KDE Plasma with bspwm?
Then there is a guide in the KDE Wiki .
