Reset git credentials and User info in Sagemaker Studio

I am working on a shared space in Sagemaker Studio. We have a repo cloned in there. Are there any way to enforce every git push to be required to enter username and password? I tried to run git config --unset credential.helper, and git config --global credential.helper 'cache --timeout=900', none of the command works. I doubt that sagemaker studio restricted to modify these configs. Also, are there any way to reset the user.email and user.name automatically? These steps are crucial for tracking commit history for a shared environment.
