Hello all,
I am currently working on a project in which I need to display a map composed of multiple background base map layers.

I have multiple sources for the tiles for which I have an associated date. I need to display the layers in order of those dates (most recent in front) as on the following schema:
For a question of performance, my question is:
Is it possible to avoid loading and downloading tiles in the background (only load "visible" ones - on the schema, for the white tile : only 2023) as we already know they will not be visible by the user?
And if possible, how?
Thank you!
