Default Controls – How can I disable controlNav and directionNav?

I am trying to disable the controlNav and directionNav controls within flexslider. I am using the risen theme from themeforest and the theme is using jquery.flexslider-min.js. If I use the full jquery.flexslider.js there is the following options that I can disable controlNav or directionNav.

How can I either disable this from my functions.php or the jquery.flexsliders-min.js?
