I spent some time making multilayered clouds to expand the height of the overworld, but when I entered the end I noticed the clouds were rendering there too.

It would be a nice feature if there was an option to black/whitelist dimensions that the clouds can appear in.

The clouds are in the nether too. And I am thinking about deleting this mod, since there should be no clouds in the End or Nether, it makes the dimensions look very weird, and the clouds break a specific type of immersion you have in the End and Nether.

It would not be that hard to add an option to disable the clouds for any dimension/world you have available on the server or single-player world you are playing on.
