Openlayers : Prevent features icons overlay

问题

I'm using openlayers (v6.4.3) to display a map with features in different layers. I want to prevent overlay of feature's icons from different layers : if two of them overlap, I have to move one of the icons. I looked on the official openlayer's documentation but I can't find an option or a method to achieve that.

Thanks for any help !
