BCM4339 Disable one frequency band

[tanvi_desai]

Hello,
I am using BCM4339 Single-Chip 5G WiFi IEEE 802.11ac MAC/Baseband/ Radio with Integrated Bluetooth 4.1 and FM Receiver which support dual band.I want to disable one frequency band(either 2.4Ghz or 5Ghz).
I found one way to disable frequency band by using mac80211 driver and using the following command:
sudo modprobe mac80211 ieee80211_disable_40mhz_24ghz=1

But when i tried to enable module mac80211 in kernel configuration it was generating the following error:

Is it possible with sudo modprobe mac80211 ieee80211_disable_40mhz_24ghz=1 command? or any other way to disable one frequency band.

Thanks,#
