Is there a way download/sync a layer that has attachments without attachments, but still allow for the adding of them?

Question

We have data collectors using ESRI collector all across a state.  Every morning they have to download a new work area - World Topo basemap, plus slice of one layer (attribute data focused), and a slice of another layer (picture/attachment focused).

We wanted to try and eliminate the download portion each morning, giving our teams and extra 15-30 minutes every day.  We found we could create a basemap of the entire state at a high enough resolution (https://community.esri.com/thread/195346-problems-using-rest-api-to-generate-tile-packages-from-world-topo-for-export ), and we can download the attribute specific layer for the entire state (takes 5-10 minutes) but we can't download the picture focused layer (pics are tie to the attribute layer through IDs we create and maintain / geographic location), because of the sheer size (GBs) of pics that would need to be downloaded. Is there a way to download an attachment enabled layer within collector, such that:

* We don't download any of the attachments when defining the work area and doing the initial pull/sync
* But can still upload new attachments to the points created in the layer that get synced at the end of the day?

Anyone know?

Is there a similar option for ArcGIS Pro when downloading a map offline? Many of the features needed contain attachments that aren't necessary for the work we are performing on a limited-bandwidth connection.

Take a look at the section Optimize download and sync in Prepare maps for offline use—Collector for ArcGIS | ArcGIS. In the item page of the map on ArcGIS Online or your Enterprise portal, the map author can specify in the Advanced Offline Options if downloading editable layers includes all the features, and if so, if attachments should be downloaded as well.
