Change lockscreen wallpaper from command line?


is there a way to change the lockscreen wallpaper with the command line like it is possible with plasma-apply-desktoptheme?

I can change the settings with kwriteconfig6 --file kscreenlockerrc --group Greeter --group Wallpaper --group org.k de.image --group General --key Image <file> but these changes only apply after the lockscreen is opend again.
