Does Jupyter Notebook update automatically?

This should be fixed by #7273

Does Jupyter Notebook update automatically?

It really depends on how the notebook package is installed. If you install notebook with pip install notebook in a virtual environment and then don't run any update command, then it should not update automatically.

However some installations (based Linux distributions for example) might indeed do it for you when updating the system as a whole.

It looks like you were using the classic notebook before. If so you may want to have a look at the migration guide to help you decide whether you still need jupyter_nbextensions_configurator or not: https://jupyter-notebook.readthedocs.io/en/stable/migrate_to_notebook7.html
The migration guide provides some information for running the old classic notebook UI if desired.
