Suppressing message 978 in an Availability Group

We are running with Availability Groups in SQL2012 SP1 with a primary and a secondary replica that will allow access if you use application intent read only which we are not doing. We probably have some automatic polling by SCOM 2012 that throws the 978 message all the time causing a large SQL errorlog full of these messages and not much else.

is there a way to suppress these 978 messages?

Thanks

Chris
