Managed navigation setting using CSOM

I am trying to Set the "Manage navigation setting" on list using CSOM, but I unable to get the Client side object for MetadataNavigationSettings. this is only available in (Microsoft.SharePoint.Client.DocumentManagement) API.

however this is possible through PS: link here http://get-spscripts.com/2011/03/configuring-metadata-navigation.html

Please refer image2, ( marked in yellow), the values are coming as part of manage navigation setting for particular list. 

and I would like to do this using CSOM.
