symfony - Override ModelListType modal

Question

I have a one-to-many relationship between parent and child on the same entity. Because the list is long, the ModelListType is easier to use because it allows searching and selecting.

However, I need to prevent a situation where when editing a parent, the user can accidentally select a child would lead into cyclic dependency.

protected function configureFormFields(FormMapper $formMapper): void
{
        $formMapper
            ->add('name')
            ->add('parent', ModelListType::class, [
            'label' => 'Parent Level',
            ]);
}

Since ModelListType class has no query property, I am thinking I can overwrite the list_select.html.twig template to be able to disable the items that should not be selected.

How would I overwrite this since it's not a field that is available for which I can create a custom template for directly?

I have attached an image of the select buttons I intend to modify.
