Is there a way to tell mypy to ignore checks on overridden functions?

Question

I changed a function in a specific library by monkey patching it with a different function.

Library's send function

def send(content: str):
  ...

Monkey patch

def new(content: Union[str, dict[str, str]]):
  return send(content)

library.send = new

But using that function results in a mypy error:

Code that resulted in an error

library.send(
  {"ja": "Japanese text", "en": "English text"}
)

Error text

Argument 1 to "send" has incompatible type "Dict[str, str]"; expected "str"

Is it possible to make exceptions for certain functions to avoid this?
