Hi Marisa,
The closest we can get to currently is to have all access in the user role turned off except for under Event > Invitee Management > Invitees turned to Full Access. This does give them access to other data points besides uploading the registrations however, the will also see Internal Information, Hotel/Air Requests, Abandoned Registrations, Uploaded Documents and Awarded Credits.
I am submitting some feedback to our product team to have this action be its own setting on your behalf.
