Hi @mac,
The metadata displayed as a part of a published article is pretty standard across the board if you’re just using OJS out of the box, and not too customizable. Typically you’ll see author name (and, if they’re available - author biographies, abstract, license etc.). In order to customize what is displayed, one would have to get involved in customizing a theme. This post has a user indicating that they’re interested in the same option for disabling author biographies: Switch off Author Biography on Article page.
For customizing themes, please see our theming documentation: PKP Theming Guide
For references, specifically, you do have the option to disable the display of these: Chapter 15: Production and Publication (please note this documentation is for OJS 3.2 - I’m not sure what version you’re using).
