How to exclude several records from a connection with an external table (ForeignKey)?

Question

Django

Good afternoon!
There is a simple model (Result) and a form that is associated with it.

class Result(models.Model):
 
    id = models.AutoField(primary_key=True)
    created_at = models.DateTimeField(auto_now_add=True)
    doc_analis = models.BooleanField(blank=True, default=False)
    doc_change_vid = models.ForeignKey(doc_vid, on_delete=models.SET_NULL, null=True, blank=True) # FK к таблице doc_vid

In the form, one of the fields is a drop-down list (foreign key)

class ResultNew(CreateView):
    model = result
    fields = '__all__'
    def get_form(self, form_class=None):
        form = super().get_form(form_class)
        form.helper = FormHelper()
        form.helper.add_input(Submit('submit', 'Create', css_class='btn-primary'))

        form.fields['doc_change'].label = "Изменение"
        form.fields['doc_analis'].label = "Анализ"
        form.fields['doc_change_vid'].label = "Вид документа"  # FK  выпадающий список (4 значения из таблицы doc_vid)
        return form

How to exclude several entries in the drop-down list (ForeignKey to the doc_vid table), for example, the first and second, leaving the third and fourth?
