Is there any pattern for being able to use mutations and not serializing typename__ for deeply nested classes?

Like the question says. I am constructing a deeply nested object using the types generated by the datamodel-code-generator. This will go into a mutation, however it generated the typename__ fields. Graphene is telling me my type doesn't have the "__typename" field. Just seems like there should be an easy default way to be able to use these generated classes for mutations too but maybe I'm not seeing it?
