Exclude/Include Any Section in Hompage Using Theme Option

Step 01: Have a 'sections' & 'settings' array like this:
IN 'sections' array, put this:
      array(
        'id'          => 'homepage_settings',
        'title'       => __( 'Homepage Settings', 'theme-text-domain' )
      )
IN 'settings' array, put this:
        array(
            'id' => 'testimonial',
            'label' => 'Show Testimonial ?',
            'std' => 'yes',
            'type' => 'select',
            'choices' => array(
              array(
                'label' => 'Yes',
                'value' => 'yes',
                ),
              array(
                'label' => 'No',
                'value' => 'no',
                ),
              ),
            'section' => 'homepage_settings',
            ),

Step 02: if your testimonial/Any other sections are not in shortcode, then use get_template_part like this in the homepage:
<?php get_template_part('testimonial'); ?>

Step 03: Create testimonial.php OR any sections AND put the content of dynamic testimonial there.
Step 04: Use the code like this in template-welcome.php OR where needed:
<?php
    $testimonial = ot_get_option('testimonial');
?>

<?php if($testimonial == 'no'): ?>
    <?php /* My Changes*/ ?>
<?php else : ?>
    <?php get_template_part('testimonial'); ?>
<?php endif; ?>
