Thanks Thomas, I wasn’t aware of pynsist. I will check it out.

Is it possible to call the bundled python interpreter from within a frozen exe?
I need to call a third-party py file which is designed to run from the command
line, not natively using import statements.
Besides what Owen suggested, you could also use a trick like multiprocessing
does with its freeze_support() function [1]. In that case, you'd launch your
subprocess using sys.executable, like when running unfrozen, but as your
application starts up, check for a particular command line argument, which
tells it to do something other than launching your application. In your case,
that would be running the third party Python script.
This is also something where my alternative tool, Pynsist [2], might be easier.
Because it doesn't freeze your code, sys.executable points to a regular Python
interpreter, and you don't need any special handling to run a Python subprocess.
