Asus rt-ac68u. Usb 3.0 wifi interference setting

Hi.

My usb3 flash drive is not working on the usb 3.0 port.

I read on this forum that disabling this parameter can solve my issue :

But i cant find the parameter in wireless/professional/2.4ghz menu.
I have 3.0.0.4.384_21045 firmware.
Maybe the name of the parameter changed ?

Thanks for your help.
