add_filter( 'facetwp_preload_url_vars', function( $url_vars ) {

    if ( empty( $url_vars['make'] ) ) { // Replace 'make' with the name of your facet
      $url_vars['make'] = [ 'audi' ]; // Replace 'audi' with the facet choice that needs to be pre-selected. Use the technical name/slug as it appears in the URL when filtering
    }
    // add more facet selections
    if ( empty( $url_vars['vehicle_type'] ) ) { // Replace 'vehicle_type' with the name of your facet
      $url_vars['vehicle_type'] = [ 'coupe' ];
    }
  }
  return $url_vars;
} );
