How to disable progressive rendering in Arnold 4.6.5?

[no188328]

Im experimenting with the Arnold toon shader but it takes me a long time to get a preview of what Im doing in the IPR as the lines and edges of objects gets rendered in the latest stage of rendering. My instructor fixed this by disabling the progressive render option in the IPR>render in Arnold 3.0.4 but I can't find this option in my version. How can I get a fast preview of my lines in Arnold 4.6.5?

The option still exists on the render settings System tab, called Progressive Refinement.
