Install a module to a specific to Python Installation (one of many))

[tester_V]

Greetings!
It is kind of confusion to explain. Sorry about that!
I have 4 different Python versions installed on a Windows machine.
Python version 3.11 is a main one, it is setup in the Envs of the PC and the other ones installed without the Envs and used by the user with the lines in the scripts:
#!"C:\Python308\python.exe"
#!"C:\Python306\python.exe"
#!"C:\Python027\python.exe"

I'd like to install a new module for the "C:\Python308\python.exe", I understand PIP would not work for the local installation. How could I install/upgrade a module?
Thank you.
