Hello,

I am trying to find out whether there is a way to suppress Defender for endpoint notification in Windows 10/11. The reason is that we run security testing regularly and I do not want to get end users disturbed by Defender notifications on their computers.

I was able to suppress alerts in “Microsoft Defender XDR > Rules > Alert tuning”, but this only affect the alerts generated in Defender portal. 

We use M365 E3 with M365 E5 Security

Thank you.
