Can't you simply place the DLLs into the PythonXX\DLLs\ directory ?

That's where Python itself keeps external DLLs (and several PYDs)
and it won't change after installation of Python.

Or create a special container package on PyPI into which you place
the DLLs and add dependencies to this in all other packages.

You can then load the DLL via win32 LoadLibrary either using the
Python win32 tools or ctypes:

https://docs.python.org/3.7/library/ctypes.html
http://timgolden.me.uk/pywin32-docs/win32api__LoadLibrary_meth.html
https://www.programcreek.com/python/example/51388/win32api.LoadLibrary

FWIW: I think this ticket has shown plenty options to possible
solutions, including many which do not manipulate the path.
