Presenter - notification quizmaker

Here is the scenario. 

1. Insert a quizmaker into the PPT slide

2. Preview the quizmaker slide

3. When you click next if you have not yet answered, the notification pops up something like this (i.e. "You must complete the quiz in order to continue") with background that covers the whole estate.

Question: Is there a way to change that background? (e.g., remove the background, change the background color, etc). 

Thanks in advance,
