Unfortunately that isn't in the UI options.
Unlike in 4.8 where many asked why they couldn't see the results and we would tell them how to display the results, there is no reciprocal setting in 5.0 were the results are displayed by default but there is no option not to display them.
Some including myself has asked if there can be a means of choosing to display or not display the results of the context menu scan, we live in hope
