How to Safely Disable Automatic Updates in WordPress
The first column, WordPress Updates, isn’t actually dealing with automatic updates. Instead, if you turn these options off, it turns off manual updates as well. For example, if you turn off Plugin updates, you won’t be able to manually update your plugins from the Plugins tab anymore. You can exclude certain users from the restrictions in the Advanced tab.

There could be several reasons you might not like the idea of automatic updates. Some developers often modify core WordPress files, or sometimes you might need to prepare your theme or plugins to make them compatible with the next update. Whatever be the case, switching to manual updates gives you a better control, allowing you to skip some minor updates (although not recommended) or updating as per your convenience.
