setblocking(False) fails on npipesocket object

I'm currently working with a socket produced by the container exec_run() function. I am trying to set the socket to be non-blocking (i.e. instant timeout if no data to receive), but running into an error when executing socket.setblocking(False).

This is an area of Python I haven't really explored before so forgive any missing detail - let me know if any more info would be helpful.

Stacktrace

Traceback (most recent call last):
  File "d:\Repositories\DockerProj\test.py", line 9, in __init__
    self.socket.setblocking(False)
  File "D:\Repositories\DockerProj\.venv\lib\site-packages\docker\transport\npipesocket.py", line 167, in setblocking
    return self.settimeout(0)

    self._timeout = win32pipe.NMPWAIT_NO_WAIT
AttributeError: module 'win32pipe' has no attribute 'NMPWAIT_NO_WAIT'

Start in docker/transport/npipesocket.py at setblocking and settimeout, where the stack trace shows the failure. Reproduce the call with a socket returned by exec_run() on Windows, then verify that setting non-blocking mode no longer raises AttributeError and produces the requested immediate timeout behavior.
