Setup is not available for the built-in System Monitor, this is by design.
If you make your own Workspace Toolbar button it can display if you put following code in your WorkSpaceToolbarPlugin
WorkSpaceToolbarPlaceDefinition.WorkSpaceIds =
new List<Guid>()
{
ClientControl.SystemMonitorBuildInWorkSpaceId
};
If my answer is unclear do an experiment. Modify the SCToolbarPlugin sample. In SetViewItemBackgroundColorWorkSpaceToolbarPlugin.cs line 63 add ClientControl.SystemMonitorBuildInWorkSpaceId to the list.
