Yes, it can be possible. Please try to keep the new option enable and put the following PHP code inside your child theme functions.php file:
if ( function_exists( 'smooth_back_to_top_button' ) && ! is_admin() ) {
add_action( 'wp_head', function() {
remove_action( 'wp_head', array( smooth_back_to_top_button(), 'internal_styles' ) );
remove_action( 'wp_footer', array( smooth_back_to_top_button(), 'add_markup' ) );
remove_action( 'wp_footer', array( smooth_back_to_top_button(), 'internal_scripts' ) );
remove_action( 'wp_enqueue_scripts', array( smooth_back_to_top_button(), 'enqueue_scripts' ) );
} );
}
Those codes will omit the plugin functionality for the site front-end. Could you please update me on that is it working for you or not?
Thanks
