Padding on page templates

Hi,

Can you tell me how I can remove the 40px padding applied to .one-container .site-content when using a page template?

Template is:

<?php
/**
 * Template Name: Home
 *
 * @package GeneratePress
 */
 
// No direct access, please
if ( ! defined( 'ABSPATH' ) ) exit;

get_header(); ?>

	<div class="smb-home-page-intro">
		<div class="inside-smb-home-page-into grid-container grid-parent">
			<div class="grid-100 grid-parent">
				<div class="grid-70 mobile-grid-100">
					<h1><?php the_field('home_page_intro_headline'); ?></h1>
					<p><?php the_field('home_page_intro_summary'); ?></p>
					<div class="smb-home-page-intro-phone-number">
						Call today to discuss your service requirements<br><a  href="tel:01234&nbsp;567890">01234&nbsp;567890</a>
					</div>
				</div>
			</div>
		</div>
	</div>

<?php
get_footer();

Site is:

I know I can adjust padding values in the customizer but this is across all pages, including those not using a template.

Thanks,
Paul.
