How to suppress specific errors from Synthetic monitoring

I have certain URLs under Synthetic monitoring, some of them are working fine but some of them are partially working. i.e., the success rate for 24hrs would be ~80-90%.
This is because they generate errors, for example “NetworkError: No route to host (Host unreachable)”

New Relic docs says, if this error is from Private minions then

But still, I can see the same error message in some of the cases. So thinking to suppress this error message to not to send alert. Is this possible through muting rule or with any other functionality in New Relic?
