Is it possible to connect to the Vu+ HDD via NFS from Kodi on Nvidia Shield TV?

I have tried enabling NFS in menu (OpenVix) and it is running. Have edited the etc/exports and restarted

/media/hdd/ 192.168.x.x/24(rw,all_squash,sync,no_subtree_check)

But Kodi on Nvidia Shield does not connect. Most NFS Vu+ tutorials are about NFS to another receiver, so I think maybe something more is needed in the config or is it possible at all?

I do not think Kodi supports NFS ver. 4
