Is there a way to run Calibre in a local Python environment？

Is there a way to run Calibre in a local Python environment instead of using Calibre's built-in Python?
Then, I would like to know if using the built-in Python offers better performance？or something else.
Is there anybody who can provide a development version that runs with the local Python environment?

Only on Linux of you either build calibre from source or use the distro calibre package, see the manual for details: https://manual.calibre-ebook.com/develop.html
