If 2.4 Ghz is not specifically needed for a site, what steps are necessary to avoid ANY interference on other 2.4 Ghz systems? Note it is preferable to LISTEN for rogues, but not essential.
1. Simply specify, for each SSID, that only 5 (or 6) GHZ is to be used?
2. Disable b/g processing ?
3. Go individually into each AP, and specifically disable slot 0 ?
If just (1) or (1 and 2) are chosen, DOES the slot 0 radio no longer transmit anything at all? No SSID's would be visible, but is the transmitter still sending anything at all (empty beacons, or other), or is (3) still necessary?

what model of AP , WLC and what code running running ?
config 802.11a disable
config 802.11b disable
if the AP in group then you can disable by group ?
If you have prime you can use template.

If there is no need for 2.4 GHz on any of the WLANs in your use case , then I would suggest just disabling it globally..
If you prefer to leave 2.4 enabled globally but there is a specific SSID you only want to use 5 GHz and 6Ghz , then on those WLANS, just set it to only broadcast on the preferred radios without 2.4 Ghz and this will do.

Don't overcomplicate it:) If you don't have a requirement for 2.4ghz, just disable it like the others mentioned. If disabled, it's disabled, the ap will not use it. Keep in mind that if folks whom own 2.4ghz at that site still complain, it can be the environment and or adjacent 2.4ghz networks or devices, not specifically yours.

The question is partly about the "wifi environment" with multiple applications and also for staging. If I am staging 50 new AP's with 2.4 and 5 disabled (in a room; getting named and IOS update) but the slots not shut down, will that potentially cause issues with nearby clients, or will they simply not be using the radios at all?

If no SSIDs are enabled on the respective controller then nothing will be broadcast on the radios from the Aps so nothing will be used if we are just naming and upgrading IOS

As long as you have disabled the radio or radios, then it is like a light switch, you turn it off, there is no light. So in your staging process, you need to make sure you have that switch off.

Just because a wireless client has 2.4 Ghz and 5.0 Ghz does not immediately mean it will not require 2.4 Ghz.
My answer to this conundrum is to enable Flexible Radio Assignment and let the controller do it's "thing".
