Render Production

The Render Production command, available on the Render flyout on the main toolbar, renders the scene using the current production render settings without opening the Render Setup dialog.
Tip: To activate Production rendering mode without launching a rendering, use the Target drop-down list on the Render Setup dialog, or the drop-down list at the top-right corner of the Rendered Frame Window.

You assign which renderer to use for production rendering on the Render Setup dialog Renderers drop-down list.
