Outlook Focused Setting

Are there any GPO or registry setting available to turn off the Focused inbox setting on Windows Desktop Outlook client? We are running Office 365 Monthly channel. We are aware that there is a PowerShell command that can be run on the EXO but we are looking for a registry key change. Try to run Process monitor (Sysinternals) but could not find out the setting that modifies the registry. Any help us appreciated.
