Can I leave unused transceiver receivers unconnected for Stratix V GX/GS/GT, Arria V GX/GT and Cyclone V GX devices?

Description
The Pin Connections Guidelines document for Stratix® V GX/GS/GT, Arria® V GX/T and Cyclone® V GX devices recommends to connect unused GXB_Rx to GND. The reason for this recommendation is to improve noise immunity. However for applications where the receiver is routed to an unused connector, the receiver would effectively be floating. In this instance it is OK to not tie the unused receiver to GND.
