You can not override protected function using plugin.

Plugin Limitations:

Plugins cannot be used with any of the following:

Final methods
Final classes
Non-public methods
Static methods
Virtual types
Objects that are instantiated before Magento\Framework\Interception is bootstrapped
Objects that are not instantiated by the ObjectManager (e.g. by using new directly).

For More Details refer Magento Devdoc


In your case, you can use Preference to override these classes which have protected mathod.
