I'm not sure if understood your use case correctly . Below mentioned are few points which i will recommend
1. If NAS mount points are required for ESXI Host which are leveraging NSX features - This is nothing but a IP-Storage connectivity which falls under a VLAN configuration.
2. If NAS mount points are required for Virtual Machines - technically you could bridge those Mount Point Vlans via Software bridge feature - Bandwidth/MTU will be a constraint and we support maximum MTU of 9000 . So it would be better to configure those mount points as normal VLAN's with MTU 9000 set at DVS.
