[keycloak-user] Disable Authenticator menu in user account service

Hello, I'm currently configuring keycloak, and i wont use OTP authenticator. But i cant make the authenticator menu not to show in user account service. i saw this sentence in the doc : "The Authenticator menu item allows the user to set up OTP if they desire. This will only show up if OTP is a valid authentication mechanism for your realm" But i dont find where to declare that OTP is not a valid authentication mechanism. Best Regards. Nicolas.
