[Python] how to gracefully ignore non-matching keyword matching arguments in python dataclass

Is there an equivalent for @dataclass that can gracefully ignore non-matching keyword arguments without having to include an __init__?

from dataclasses import dataclass

@dataclass
class MyClass:

my_class = MyClass(20, **{"kwarg1" : 1}) # TypeError: MyClass.__init__() got an unexpected keyword argument 'kwarg1'
