Sonata provides you with the 'sonata_type_choice_field_mask' type which allows you to change the fields displayed on the form dynamically depending on the value of this 'sonata_type_choice_field_mask' input so you don't have to use ajax.

Here is the doc where you can find everything about sonata types and the choice field mask.

protected function configureFormFields(FormMapper $formMapper)
{
    $formMapper
        ->add('type', 'sonata_type_choice_field_mask', array(
            'choices' => array(
                //The list of available 'Type' here
                'choice1',
                'choice2'
            ),
            'map' => array(
                //What you want to display depending of the selected option
                'choice1' => array(
                    // List of the fields displayed if choice 1 is selected
                    'field1', 'field3'
                ),
                'choice2' => array(
                    // List of the fields displayed if choice 2 is selected
                    'field2', 'field3'
                )
            ),
            'placeholder' => 'Choose an option',
            'required' => true
        ))
        ->add('field1', 'entity', array(/* Options for entity1 goes here */))
        ->add('field2', 'entity', array(/* Options for entity2 goes here */))
        ->add('field3')
    ;
}
