Suppress Alert mail from Appian to end user.

Hello Everyone,

We have got an requirement to suppress the alert message like "commented on the system event from "Application_Name"" in Appian 17.4 Version.

We are positng a news feed and whenever the news feed is getting updated by any other source (from approval flow we are adding a comment to the entry).

They basic user who has created the request/feed entry who getting Appian alert stating that "....commented on the system event from "Application_Name".

Is there anything with Properties setup to control over alert like this from enviorinment or Is there anything needs to change in design level ?

Please advise.

Thanks
