There are some well-known options for preventing the front end from adding "unnecessary" stuff to .nb files when keeping them e.g. in a git
However, recent Mathematica versions seem to add an
ExpressionUUID to each cell,
which makes the task of keeping .nb files in a repository more challenging.
So is there perhaps some dedicated option to turn that off and therefore get rid of
ExpressionUUID in a given notebook?
Edit: Here is an example of a notebook created with Mathematica 12.0 that contains
