The SystemExtensions payload is new to macOS 10.15 and described here:
https://developer.apple.com/documentation/devicemanagement/systemextensions
com.apple.system-extension-policy is the payload type
How do I use macOS Server's Profile Manager to create/edit such payloads? If find no "System Extensions" settings.
There is an "Extensions" payload in Profile Manager but this is for com.apple.NSExtension payload type and doesn't work to allow system extensions.
Thanks!
