How to change the default image size for custom post type in WordPress

Inside Admin panel when we upload image for a specific post that image has default size medium(300 X 300). Instead of changing it every time from Add Media > ATTACHMENT DISPLAY SETTINGS while inserting into post or from Edit > Image Details >DISPLAY SETTINGS after inserting into post. How can we set the default image size to full/ original size or if it's full size then to medium/ thumbnail.

The main thing is to change the default image size setting. How do I do it?

Did you want to full image display on front-end post? – Purvik Dhorajiya
yes but without changing it every time from ATTACHMENT DISPLAY SETTINGS & DISPLAY SETTINGS as mentioned in the question. – Yash Sharma
the_post_thumbnail('full'); have you try this function to display post image ? – Purvik Dhorajiya

function custom_image_size() {
    //set default for image size
    update_option('image_default_size', 'full' );
}
add_action('after_setup_theme', 'custom_image_size');

or simply

update_option('image_default_size', 'full' );
