For a check-in/check-out Repository under Azure, you'll be looking at either an Azure Repos solution under DevOps, or GitHub. SharePoint also has Version Control for documents and files.
Options for file based configuration library in Azure

I am required to provide a library type deployment that contains file base configuration that can only be edited using third party external tools, so no code tweaks etc. are required/permitted as part of the library. Users are required to check in/out configuration files, add comments, and request reviews of changes.
There are various GIT options available, is there any option to have this functionality external to a devops solution?
