You need to check for the post type you want to change inside your function

add_action('acf/save_post', 'save_post', 20);

function save_post($post_id){
    
    if (get_post_type($post_id) != 'post') {
      return;
    }
    // Get the data from a field
    $one = get_field('one', $post_id);
    
    // Set the post data
    $new_post = array(
        'ID'           => $post_id,
        'post_title'   => $one,
    );
    
    // Remove the hook to avoid infinite loop. Please make sure that it has
    // the same priority (20)
    remove_action('acf/save_post', 'save_post', 20);
    
    // Update the post
    wp_update_post( $new_post );
    
    // Add the hook back
    add_action('acf/save_post', 'save_post', 20);
  
}
