Thanks so much. For anybody interested here is the diff patch with version 1.2.9:

I agree this should be a setting in the admin panel instead of a filter that developers.
The file is located here:
wp-content/plugins/give/includes/gateways/offline-donations.php
But you shouldn’t modify the plugin files directly because if you upgrade it you’ll loose all the changes.
You should modify the child theme like this:

In my instance, I found a file that is similar to functions.php in my child theme and added the filter code at the end and tested that worked.
