IR302-FQ38-WLAN band locking

Hello All,

I use an IR302-FQ38-WLAN router with Verizon in the U.S. The router uses any of bands 2, 4, or 66 in my location. Is there a way that I may specify which bands the router will use? Any way to do band locking. It is OK with me if command line (CLI) is required. I have firmware V3.5.37.

Thank you for your help.
