Is there a way we can block certain actions for users such as -
Block External action for "Amazon S3 command, “Download File”, “File Transfer”, “Google/OneDrive Command” via the registry somehow ?
Also is there a way to block checking for updates of Easy Morph. We will be running EasyMorph on a non-persistent Citrix Virtual Apps and Desktops server so we do not want users trying to update the software
Blocking certain actions in EasyMorph isn't possible. Although, the specified actions require a connector. If you use EasyMorph Server, you can restrict users from editing existing connectors or creating new connectors in a Server space. Note, however, that advanced users may still be able to switch to a local repository file (instead of using a Server repository) and create connectors there.
Besides that, you can hide certain actions in the action catalog. Right-click an action, and select "Hide action". That won't disable hidden actions, but will make them less discoverable.
