How to exclude some files in a git repository from being affected by the -a option of a commit command?

Question

git

There are files in the remote repository that should be stored there, but should never change. However, they are automatically changed while working in the local repository. As a result, git in response to the status command honestly indicates that they have been changed and the changes are unstaged. These changes cannot be committed, so I am deprived of the ability to use commit -a for all other files, which is convenient. Including these files in .gitignore does not help in any way.
How can I force git to still version files, but not keep track of the difference between their current state and the state in the staged-area?

Answer 1

The official manual recommends git update-index --assume-unchanged
