Disable Share to Outlook in a Chat or Channel conversation

With the Outlook integration features enabled you can effectively bypass a workspace channel discussion privacy control using Share to Outlook and forward conversation in email

I know you could use snippet or cut-n-paste *but* CISO want to know if we can disable this feature, without crippling or disabling Outlook for the web. (background on this article: https://docs.microsoft.com/en-us/microsoftteams/teams-outlook-email-integration#share-to-outlook  )

Does anyone know if there is a control for this, using powershell or equivalent? ( there isn't in the admin.teams.microsoft.com UI )
