Hi Dehbi,
As far as I know, there may be no option to do this.
As a workaround, you can set "My delegates only" in your Outlook so that the meeting requests will be sent only to your delegate if all the meetings are processed by your delegate.

You may also set a rule to delete meeting requests but you can still find them from Deleted Items if you need to check from time to time.

Hope this helps.
Regards,
Perry Pan
