What will happen if I turn off `Git Large File Storage`?

I already turn on Git Large File Storage for a while,but through several days test, git lfs function has lots of problem.
Then I decide to turn off Git Large File Storage,does the files tracked by git lfs moe to gitautomatically ?
I just want to ask this question as my first question.

Also contemplating this as an option if anyone knows.

Is there command or places to check to see if LFS is being used. I’m on a self-hosted GitLab (v13.x). One place I see if uploading through the GitLab UI is this location: /var/opt/gitlab/gitlab-rails/shared/lfs-objects
