Excluding fields on a pydantic model when it is the nested child of another model

I have a pydantic model that I want to dynamically exclude fields on.

I can do this by overriding the dict function on the model so it can take my custom flag, e.g.:

class MyModel(BaseModel):
  field: str

  def dict(self, **kwargs):
    if ('exclude_special_fields' in kwargs):
       super().dict(exclude={"field": True}, **kwargs)

    super().dict(**kwargs)

However, this does not work if my model is a child of another model that has .dict called on it:

class AnotherModel(BaseModel):
  models: List[MyModel]

AnotherModel(models=[...]).dict(exclude_special_fields=True) # does not work

This is because when MyModel.dict() is called, it isn't called with the same arguments as the parent.

I could write a dict override on the parent model too to specify an exclude for any child components (e.g. exclude={"models": {"__all__": {"field": True}}}), but in my real world example, I have many parent models that use this one sub-model, and I don't want to have to write an override for each one.

Is there anyway I can ensure the child model knows when to exclude fields?

Extra context

Extra context not completely important to the question, but the reason I want to do this is to exclude certain fields on a model if it's ever returned from an API call.
