Prevent Hass from register some components via Alexa

Somehow Hass automatically registers all my Tradfri bulbs with Alexa - as they are already connected via Tradfri Gateway diretly Alexa now is unable to use them as names are assigned twice
How can I tell Hass not to register some of the Tradfri bulbs or change the names that Hass uses to prevent duplicate names?

Thank you
Paul

Use emulated hue hidden as part of your customize entries

Thank you
i was trying this in customize.yaml but always see a config error ??

customize_glob:
“light.flu*”:
hidden: true
emulated_hue_hidden: true
homebridge_hidden: true

format your code correctly so we can see any errors. highlight code in the editor window then use the </> in the bar at the top.
