Is it possible in the Active Admin form to allow a new record to be added if there are no records yet?

Question

Ruby on Rails

Please tell me if it is possible in the Active Admin form to allow adding a new record if there are no records yet. It is necessary for me that there was only one record. And if there are no records, then only then what would be the opportunity to add a new one.

Now Add new contact always appears, regardless of whether there is a record or not
