I can’t find any explicit statements. But I am certain that the normal edition is the base game and the Archaeologist Edition includes the Echoes of the Eye DLC. I doubt there is any new content. Also it would not be possible to have the DLC on it’s own, if I understand your question correctly
Are you trying to be subtle? If not then a modded switch and a program to dump a title do the job. If you are trying to be subtle then the internet.
