Disable 2.4Ghz on vSZ-H 5.1.2

[apogee_engineer]

Hello, I want to know if there is a way to completely disable 2.4GHz per AP Group.

I have created 3 other AP groups (One for 1,6,11GHz Channels) but I cannot seem to figure out how to completely disable the 2.4Ghz for my last profile.
Any help would be greatly appreciated
