KDE can have multiple activity, and every activity can have different
wallpaper (even different plugin). And wallpaper is supported via
plasma plugin.
So I would suggest you to implement a wallpaper plugin to do this,
which can even gives you more freedom for control.

Some tutorials are here.

Otherwise you can only use some hack way to modify kconfig
(kwriteconfig / kreadconfig via CLI, or using code) . I'm not sure
which key will work for the default plugin.
