Create a Template with Header / Footer but no sidebar

Hi,

I need to upload a template that has a header / footer but no sidebar.
This is for a real estate plugin I use that has property pages scraped from a central server which are then dropped into my theme. It comes with its own sidebar so I need to disable the sidebar… but since these are virtual pages on my site there’s no way to go into each page and set the sidebar setting.
It pulls the sidebars from somewhere in the theme templates ? section and they appear as a dropdown menu in the plugin options… so I would like to upload a template to Enfold that would appear in this dropdown.

I do have one custom template that a developer created and it’s showing in my child theme under appearance –> theme editor. I do not use this template so maybe I could just customize it? Code is below…

Thanks,
Rob

<?php /* Template Name: IDX w/Sidebar */ 
	global $avia_config, $more;

	/*
	 * get_header is a basic wordpress function, used to retrieve the header.php file in your theme directory.
	 */
	 get_header();
?>

		<div class='container_wrap container_wrap_first main_color <?php avia_layout_class( 'main' ); ?>'>

			<div class='container test'>

				<main class='template-page content  <?php avia_layout_class( 'content' ); ?> units' <?php avia_markup_helper(array('context' => 'content','post_type'=>'page'));?>>

                    <?php
                    if(!empty($avia_config['conditionals']['is_builder']))
					 {
						$avia_config['conditionals']['is_builder_template'] = true;
						get_template_part('template-builder');
						exit();
					 }
					 else
					 {
						get_template_part('page');
						exit();
					 }
                    ?>

				<!--end content-->
				</main>

				<?php

				//get the sidebar
				//$avia_config['currently_viewing'] = 'page';
				get_sidebar('IDX');

				?>

			</div><!--end container-->

		</div><!-- close default .container_wrap element -->

<?php get_footer(); ?>
