Avoid sending default fields in request body of alert notification webhook

Currently, when the webhook gets fired from grafana, it sends following as the request body. However, I wanted to know if it is possible to avoid sending fields like dashboardId, evalMatches, etc. Basically, I just want to send the tags field from below. Is it possible? If yes, where can I read about the details of removing other fields? I saw docs/stackoverflow, didn’t find any. Thanks in advance.

  "message":"Notification Message",
  "ruleName":"Panel Title alert",
    "tag name":"tag value"
  "title":"[Alerting] Panel Title alert"
