NetMetal ac2 Default Wireless Band?

Hi all, I’ve a p2p link with Netmetal ac2 bridge mood. It always connect 2.4ghz first and data always pass through 2.4ghz, if I disable 2.4ghz then 5ghz passes the data. How can I use 5ghz first? I mean if 5ghz failed to connect then 2.4 GHz will activate. I need 5ghz as a default wireless band and 2.4ghz as backup… anyone help? Normis, would you please give me any solution?
Regards.

Create Connect List and determine the order in which they are connected
