How to disable Addon Domains in UI only?

view story

http://forums.cpanel.net – Hello. We want to create our own UI to manage addon domains, which talks to our API, which in turn uses API2 to create and manage domains. We want to avoid the situation when a client uses a native cPanel UI to manage domains because we need to track these domains in our database. When we disable 'Addon Domain Manager' feature via Feature Manager in the default feature list, then the API access to addon domains is also disabled. Is it possible to disable only addon domains UI, leaving API available? (HowTos)
