[v4.1] Serialized model's relation property name

[e-e]

Assuming I have a model that has a relation such as:

class MyModel extends Model {
  myRelation() {
    return this.belongsTo("App/Models/MyOtherModel");
  }
}

Right now, when loading the relation, this gets serialized as:

{
  "myRelation": { ... }
}

Is it possible to configure this relation to be serialized using snake case instead? For example:

{
  "my_relation": { ... }
}
