Hi Alejandro,
If you go to configure > common objects > new (or clone an existing 5GHz profile) > under the "channel selection" section you'll see a channel width dropdown.
Save the radio profile. Select the AP(s) > edit > interface settings > wireless interfaces > wifi1 > change the radio profile > save > update AP.
