Do DLCs have to be uploaded to the store

Hi all, had a quick question about DLCs/the documentation. The Oculus Add-On Documentation says, "If your Add-on requires additional files that are not provided in your main app package, such as DLC, you must upload these to the Meta Quest Store." Does this mean that all DLCs must be uploaded to the Oculus Store, and have to be listed on the store? Is there no way to upload a DLC asset file without reuploading the whole game, have it purchasable from my game directly, and not have it listed on the store?
