required => false Do not offer

    What does not like required = false ?

    Otherwise, you need to edit already at the level of the widget output. I don't know which engine you use, but I guess twig. Then the output should be approximately as follows:

     form_widget(form.document_type, {attr: {required: false} })

    Instead of false, you can try null.
