                'route' => ['route', 'parameters'],
                'uri' => ['uri'],
            ],

With configureFormFields you can change fields or group fields inside a form, but if you want to add a class to the whole form, I suggest you to use a template, to define in configuration

sonata_admin:
    templates:
        # default global templates
        layout:  "@SonataAdmin/standard_layout.html.twig"
        ajax:    "@SonataAdmin/ajax_layout.html.twig"

        # default value if done set, actions templates, should extend global templates
        list:    "@SonataAdmin/CRUD/list.html.twig"
        show:    "@SonataAdmin/CRUD/show.html.twig"
        edit:    "@SonataAdmin/CRUD/edit.html.twig"
