As the person creating an event, simply create an Appointment (in Outlook 2016) or an event with no attendees in Outlook on the web with the “Send a meeting invitation to group members” unchecked.
Doing so will make sure the events stay only in the Group calendar, and is perfect for FYI items like out-of-office.

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.
Thanks to everyone for your feedback and votes on this item. We’re working through a couple of options and hope to have more information shortly. It’s a very difficult problem to solve since group membership is consumed across many different aspects of Microsoft 365. Thanks for your patience and keep the feedback coming!
