It's not so clear how git commands can be used here as there is not .git directory inside HA's installation. Maybe patch is a more promising approach.
However, please note that the patching process should determine if something was changed, so it can also initiate HA's restart. Otherwise, it shouldn't initiate HA's restart to prevent an endless loop of restarts.
Anyway, I'll let you figure it out. Please let me know if you want my involvement earlier in the process.

Is your feature request related to a problem? Please describe.
I want to be able to patch sections of a file, e.g. https://github.com/schmittx/home-assistant-eero/pull/95/files
Describe the solution you'd like
Git has a robust diff and patching scheme: https://www.specbee.com/blogs/how-create-and-apply-patch-git-diff-and-git-apply-commands-your-drupal-website
Describe alternatives you've considered
Right now I've manually updated the file in my custom_integrations folder, but on update those changes will be wiped out.
Additional context
I just sat down to build a HACS plugin that uses git patch files to apply patches to HA Core & HA Integrations and saw that you've already written this extension which seems to strictly replace files.
Before I go down the path of creating a new extension which would have overlapping utility to your I thought I'd reach out and see if you were interested in extending this integration to include git diff/patch support. The unknown, for me, is if git is available in HA or if it'd need to be installed alongside the integration (that'd be a potential sticking point)
Random aside: for your file checks instead of using ~file_lines == other_file_lines, you can use the hash value / md5 checksum. Although w/ git diffs the files could have changed and as long as the patched lines weren't impacted the patch would still apply.
