Temporarily disable argocd notifications

[bodanesemateus]

I have somes applications in argocd, and one of them have a sync-window. It turns out that while sync-window is activated I continue to receive alerts.

I tried to create some logics with go in the alert trigger, but without success.

Also, I have situations where some services are turned off at night to reduce costs, but I haven't found any way to disable the alert without using a cronjob to add/remove annotations.

---

How can i deactivate the alarms while sync-window?

What's the best way to disable alerts without using a cronjob?

Is there something native to Argocd Notifications that I missed?
