Do Not Disturb / Favorites - How do I disable them?

[N2myN2]

I'm trying to set up my "Do Not Disturb" feature in "Sounds and Vibration" settings.
I want to only allow "FAVORITES" to be able to get through during my do not disturb period.
My problem is that I have over 300 contacts and they all have the favorite "STAR" highlighted.
Is there any way to "unstar" them all at once?
Thanks.

OK, I figured it out.

Go to Verizon Cloud and find CONNECTIONS and select contacts. From the three vertical dots touch SELECT Contacts. From the check mark touch O SELECTED and touch SELECT ALL. Over to the top right again touch ADD TO FAVORITES. Go back and SELECT ALL again and touch remove from FAVORITES.

Thanks.
