Turning off YouTube 'suggested videos' in the Coursepress 'featured video'

On the 'featured video' associated with each Coursepress Pro course, there is no way to turn off YouTube's 'suggested video' feature that shows random and sometimes distracting suggestions for OTHER videos on YouTube when the featured video concludes.

All other videos in the CoursePress Pro system have this function turned off. And if it can't be turned off for the featured video, I'll just not use videos there.

Any setting I'm missing? Or is there a way to modify the code to avoid this issue?
