How to remove "Submitted From"?

I want to remove the “Submitted From” field. I read in another thread, that I cannot use add_filter('cfdb_form_data', 'remove_field'); because it is generated after this filter is called:

The “Submitted From” field is generated by CFDB after the cfdb_form_data filter is called. So it does not yet exist at the time your code is called.

So how can I remove it? Where do I need to manipulate the entry?
