Hiding fetch quest map markers

Is there a way to hide all of the "fetch" or "collection" quest map markers?

Once you spot a Shard on the map, the map marker will continue to appear. Is there a way to hide all of them?

You can see here that there are many map markers that show the locations of shards and whatever and once you get a lot of them showing at once, it can really clutter the map even when you have another quest marked as the active one.
