WordPress: Override parent theme class function in child theme

I want to override function in child theme, which is defined inside a class in parent theme.

Here is the sample code:

class A extends B
 function __construct()
 $this->add_ajax('sync_post_data', 'need_to_override');
 
 //other functions
 function need_to_override()
 //function code

Additional Information:

Class B extends Class C and Class C is the root class where add_ajax is defined.

What I've tried:

As the function is not pluggable so I can't override function directly in child theme.

Secondly I tried to remove ajax action and add my custom action. It throws 500 internal server error.

remove_action( 'wp_ajax_sync_post_data', 'need_to_override' );
add_action( 'wp_ajax_sync_post_data', 'custom_function' );

function custom_function()
 //function code with my custom modification

Any help please...

You can just override that method of class in just two simple steps.

Here's how:

Open child theme functions.php

Create new class like this:

add_action( 'after_setup_theme', function() 


 class D extends A

 function need_to_override()
 //original function code with your custom modifications
 

 

 new D();
);

PS: It will work but I'm not sure if it is the best way or not!
