According to that article, the organizational default is set (to "off") with this command:

Set-OrganizationConfig -FocusedInboxOn $False

It says that the mailbox-level property has preference over the org level so you can have it disabled for the organization but individual mailboxes could still be enabled to use it. If the 'FocusedInboxOn' mailbox property is not set (not set to either True or False) on any given mailbox, then it will default to using the org-level setting.

If you wanted to also disable it at the mailbox level for all mailboxes in your tenancy, you could use this command:

Get-Mailbox | Where-Object {$_.RecipientTypeDetails -ne "SharedMailbox"} | Set-FocusedInbox -FocusedInboxOn $False
