Knowledge Management in UCI Interface

Hi,

Knowledge Base in the version 9.x says we can edit articles only the Customer Service Hub App which is an UCI interface. Please let me know if we can edit articles in the non UCI interface because we are using the non UCI interface for cases. We cannot switch to UCI just for knowledge articles. 

Also, please let me know if we can hide the global buttons like advanced find, global search etc in UCI interface. 

Thanks.
