How to select all items that have zero child rows for a particalar relation

[binary64]

Suppose I have query { people { pets { id name } } }, is there a way to select all people that have no pets?

Many thanks in advance

query {
  people(where: {_not: { pets: {} } }) {
    name
    pets {
       id
       name
    }
  }
}
