Allow to change the default configuration about the "Add to your Outlook calendar" checkbox

Since the implementation of the "Add to your Outlook calendar" checkbox option when creating a meeting in the portal, at the bottom left of the "Meeting space booking form" (see attached file)

--> This option is enabled by default, I mean that the checkbox is checked.

Would it be possible to uncheck this checkbox by Default ?
--> So that only users who are interested with this option manually check it by themselves ?
