While my phone is set on do not disturb except for contacts, my garmin still notifies me when non-contacts call me. How can I get that to stop?

I have a Fenix 5 Sapphire edition and for the most part really like it. 

My issue is that I've gotten a lot of spam calls lately.  On my phone, I turned on do not disturb except for contacts and my phone does indeed stay quiet.  However my watch still shows notifications for every spam call.  I'm getting like 3-10 spam calls every day and its really annoying.  I'd like to make my phone's do not disturb apply for my watch, so I don't have to turn my watch itself on its separate 'do not disturb' mode. 

Is there any way I can do that?  Make my phone's do not disturb also apply to my watch's notifications? 

Thanks so much!
