Prevent screen burn while using Split View

I use a display that is sensitive to [screen burn](https://en.wikipedia.org/wiki/Screen_burn-in) . The content of my screen changes frequently enough, except for one thing. The bar separates two application windows when using [Split View](https://support.apple.com/en-us/HT204948) . I started moving the black bar a bit to the left and to the right manually, but I forget to do this all the time.  Does anybody know how to still use Split View, while preventing screen burn at the same time?
