Disable SignIn / Sign Out (Adobe Acrobat DC)

How can the menu item " SignIn / Sign Out " ( Menu : Help > SignIn / Sign Out ) are hidden / disabled (Adobe Acrobat DC)?

Currently, the following data in the JavaScript file is stored:
app.hideMenuItem("DetectAndRepair");
app.hideMenuItem("OnlineSupport");
app.hideMenuItem("LearnProduct");
app.hideMenuItem("About");
app.hideMenuItem("AboutAdobeExtensions");
app.hideMenuItem("endAboutPlugInGroup");
app.hideMenuItem("SystemInformation");
app.hideMenuItem("endGuideGroup");
app.hideMenuItem("endUsingGroup");

Or can "SignIn / Sign Out" ( Menu : Help > SignIn / Sign Out ) are disabled on the registry ?
