Theme Ridge Portfolio

Hi everyone
I’m using theme Ridge (https://themetrust.com/themes/ridge/)
I have three pages which i want to show 3 different types of portfolios. However Ridges shows every skill (type) on every page. Is there a way to separate these skills per page?

Is there some php-code I can add to the template file?
see below:

<?php
/**
 * Template Name: Portfolio
 *
 * @package Ridge
 * @since 1.0
 */

get_header();

?>

	<div id="primary" class="content-area middle portfolio">
		<main id="main" class="site-main" role="main">

			<?php

			// Don't show the description for the front page
			if( ! is_front_page() ) {

				while ( have_posts() ) : the_post(); ?>

					<div id="portfolio-content">
                        <header class="entry-header">
                            <h1 class="entry-title"><?php the_title(); ?></h1>
                        </header>
						<?php the_content(); ?>
					</div>

				<?php endwhile;
			} // if

			/**
			 * Set up the skills and projects
			 *
			 * @see inc/template-tags.php
			 */

			// FilterNav output
			ridge_filter_nav();

			// Get the projects WP_Query object
			$projects = ridge_posts_setup( 'project' );

			?>

			<div id="projects">
				<div class="thumbs clearfix">
					<?php  while ( $projects->have_posts()) : $projects->the_post();

						global $ttrust_config;

						// Get the skills for each project for the .js data attribute
						$skills = ridge_get_tax( $post );

						get_template_part( 'content', 'project-small' ); ?>

					<?php endwhile; ?>
				</div><!-- .thumbs -->
			</div><!-- #projects -->

		</main><!-- .site-main -->
	</div><!-- .content-area -->

<?php get_footer(); ?>

Many thanks in advance!
