Temporarily Remove Wallpaper

Is there a way (maybe trough some app) to temporarily remove the wallpaper/lock-screen image with a simple button press (either widget or notification bar button)? By this I mean to set it to blank, or default image. I need this as I use my phone for both personal and business. During business time I'd like the possibility to easily remove my personal wallpaper, without having to to the settings every-time and resetting it.
Might there be a feature or app for android which can do this? I am running Android 9
