I posted a little about this in the #macos channel of BigFix Slack earlier. Reproduced here in case it’s helpful for folks. We don’t have MDM at my org, so this was my BigFix-y solution:
Use Apple Configurator to sign it with my org’s developer cert
Use BigFix to install it via the profiles command
Use this relevance to determine if it’s there: not exists file "/Library/Managed Preferences/com.microsoft.autoupdate2.plist" whose (string "HowToCheck" of dictionary of it = "Manual")
