Hi Marisa,
There is not a way to remove the add to calendar link from within sessions in the Attendee Hub. I would recommend submitting this as product feedback within Participate > Ideas.
You do have the ability to change the word "Included" within Marketing > Language Management > Click into the Event App and search for Included and then you will be able to change it to your own custom text instead. You'll want to do the same for the Attendee Website as well. Customizing Text in Attendee Hub
