There are 2 choices you can use are as follows...

1.) If you are comfortable with adding script to your wp-config.php file, there is an option for adding the following:

/* Allow only minor WordPress updates */
define( 'WP_AUTO_UPDATE_CORE', minor );

with the complete instructions offered right here: https://www.machothemes.com/blog/disable-automatic-updates-wordpress/

2.) And the other option is a plugin that I have spent days trying to find:

Where you will find that you have the option to “Allow minor auto updates” so that your website will remain safe because you are allowing small bug fixes and security updates.

This will provide you with the opportunity to backup your website fully BEFORE updating to version 5 of WordPress once it is rolled out.

Make SURE you install Webcraftic Updates manager as the other available plugin shuts down all notifications too. I learned that the hard way.

If version 5 breaks your website, you can simply restore your website with your backup file and let WordPress know their version 5 broke your website. Be sure to keep screen prints of any prompts you receive and provide them with your ticket so you can help WordPress fix the errors.

Hope this helps you.
