2.4 band Separate SSID

Hi

I have a Broadlink Mini 3 that needs a 2.4 band in order to set it up. The Broadlink will detect a  5.0 band and because it's not compatible it won't connect to the network.

Is there a way to broadcast a 2.4 SSID (not the current mix of 2.4 & 5.0)

In other words, can I separate the 2.4 and 5.0 SSID's so I  may connect to the 2.4 band only?
