Enable automatic minor core updates when root of site is a git repository

I have a client site that’s under version control using Git. The single repository is at the WordPress root level, but it is set to ignore everything except for theme and plugin files. I did some research into best practices and found some content on submodules, which I might try next time, but at the moment, I’m wondering if there’s a way to achieve both of the following:

1. Keep the Git repository structured as is at the WordPress root but effectively only use it to version control theme and plugins in a single repository.
2. Enable automatic WordPress core updates and get around this error: This site appears to be under version control. Automatic updates are disabled.

Adding this filter in a must-use plugin or functions.php will allow automatic updates even if the site is under version control:

add_filter( 'automatic_updates_is_vcs_checkout', '__return_false', 1 );
