Probably not.  The firewall is part of the kernel since it works
directly with the network drivers and the packets in memory (to avoid
copying data).  MS has an API for interacting with it, and controlling
and extending its behavior using an API:
https://docs.microsoft.com/en-us/windows-hardware/drivers/network/windows-filtering-platform-architecture-overview

This is what third-party firewall managers use.

Possibly Python could interact with portions of the firewall engine via
the callout API.
