NixOS is designed so that updates won’t break the system in non-reversible ways. If an update didn’t work out well for you, you can always roll back to the previous version and withhold the update until you’re ready. I’ve used NixOS as a daily driver myself for years, and hadn’t needed a reinstall even once.
