Can I disable new New Outlook (Pre) to all users?

Hi,

can I completely disable the use and update to a new Outlook desktop for all the users in Tenant?

Can i use just targeted users for testing, and completely block the rollout of the new Outlook? (I know there is an option in Microsoft 365 Admin Center for targeted users).

Thanks.

    Seeking to do the same. So far came across this to hide the 'Try new Outlook' toggle button.

    https://learn.microsoft.com/en-us/officeupdates/current-channel#outlook-1

    HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Outlook\Options\General REG_DWORD “HideNewOutlookToggle” 0 (default) - “Try the new Outlook” toggle, if available in selected update channel, is displayed to users. 1 - “Try the new Outlook” toggle is hidden.
