override woocommere function

I am trying to override includes file , like class-wc-checkout.php. I have added custom code in function create_order(), and there is a updation of the plugin. I want to update it but the custom code will be replaced with new code if i updated it.

Can i override the complete file using child theme or any workaround. Or how can i override function create_order()
