Change `inspect` Signature of Modules

Consider a nn.Module-derived class A.
Then using signature from the Python inspect module

>>> print(inspect.signature(A))
(*input, **kwargs)

appropriately produces the signature of the the forward method of torch.nn.Module.
Is it possible to change this behavior to more accurately reflect the signature of the callable A?
E.g., if the forward-method of A reads

def forward(a, b, c)

is it somehow possible to get

>>> print(inspect.signature(A))
(a, b, c)
