Any way to disable /a/g rates using 'iw'?

I notice the iw dev wlan0 set bitrates takes legacy-2.4 and legacy-5 as an argument.

Is there any way to disable all /a/g rates on 5Ghz? Basically, I want to force the interface to only us /b rates even if the AP it finds is on 5Ghz. I would expect in this case that it would just fail to associate.

Thanks,
Ben
