"Scan with windows defender" missing from contextual menu.

Question

Hello,

I have a particular folder that I want to be able to scan whenever I need to. But I am still missing the "Scan with Windows Defender" in the contextual menu when I right click on a folder. Am I missing a Group Policy setting for windows defender that I need to enable? https://www.kapilarya.com/fix-scan-with-windows-defender-missing-in-windows-10

I don't have "scan network shares" enabled on purpose because that can take awhile because of the amount of data we have. But is there a way that I could to that with a script to scan a particular network share. Or if I can make windows defender scan a particular share every hour?
