How to block *.pdf.msi in Microsoft Defender

Copper Contributor

I was reading through security news and came across this article https://www.bleepingcomputer.com/news/security/microsoft-teams-phishing-pushes-darkgate-malware-via-...  There is a known file type of .pdf.msi that we as a company are wanting to block. We would want to add a wildcard in front of that extension to block anything under that file name. Can someone help me as to how I would do this in Defender?
