Disabling the welcome mail is possible with an extra parameter in the Set-UnifiedGroup cmdlet in Exchange PowerShell: -UnifiedGroupWelcomeMessageEnabled:$false. See https://docs.microsoft.com/en-us/powershell/module/exchange/users-and-groups/set-unifiedgroup
Use this as a part of a custom group creation flow if you would like to restrict and/or customize the welcome mail for many groups across your tenant.

Is there any way to not rely on global settings and have the ability to elect this notification to not send at the point of adding members. I am creating a group with over 300 people and don't want them to receive the notification prior to getting a formal communication to explain the purpose of the group.
