Better to put everything in git and run your own renovate bot which will create PRs for you to review and also pull in the changelogs to the PR itself so you can check for breaking changes.

Just set Watchtower to quit after run and run it manually when convenient. This way, you’ll instantly know if some update went wrong and can fix it.
