The Linux client "kind of" has a "sync to odrive" feature. It allows you to define an arbitrary local mount point and remote destination. You can only define one, though.
The agent "mount" command is given a local folder and a remote folder. It created a sync relationship based on that.
Alternatively, there are folks that will map their NAS as a network volume to Windows or Mac and then use the odrive Desktop "sync to odrive" for that.
