I have User which is tied to Company through "company_id" field.
I don't like default dropdowns bc they get too big if not using ajax feature, but if using ajax feature it seems I cannot set None as value for field.
Here is the code and the admin

class UserAdmin(ModelView, model=User):
    ...
    form_columns = ["email", "company_id"]

During build-up, we are setting data-allow-blank to 1, but never using it in JS.
