Remove Calendar Attachment from Alert

Summary:

Hi everyone,

We have enabled the alert called "Offering Definition has Changed" (WLF-00002), and we were able to successfully remove the calendar (iCalendar) information from the body of the notification. However, the calendar file (ICS) is still being attached to the notification email.
We would like to completely remove the calendar attachment as well — is this possible?

Has anyone managed to remove the calendar file from an alert notification entirely?
Any guidance or documentation reference would be greatly appreciated.

Thank you!
