Hello!

You could try adding the below code to your child theme’s functions.php:

// Example filter to alter Poka Metabox Field "Affiliate Rating" (pokafield_affiliate_rating)
add_filter( 'poka_metabox_field_pokafield_affiliate_rating', 'poka_child_637f2f4047a75' );
function poka_child_637f2f4047a75( $field ) {
	// Change the field max to 10
	$field['max'] = 10;
	return $field;
}

function poka_affiliate_rating( $review_id, $atts = array() ) {

	$html         = '';
	$count        = 0;
	$rating_num   = poka_affiliate_rating_number( $review_id );
	$rating_icons = poka_affiliate_rating_icons();
	$half_icon    = apply_filters( 'poka_affiliate_rating_half_icon', true );

	if ( $rating_num ) {

		if ( in_array( 'rating_num', $atts ) ) {
			$html .= '<div class="review-rating">';
			$html .= '<span><strong>' . $rating_num . '</strong>/10</span>';
		}

		$html .= '<div class="rating">';

		$rest = 10 - $rating_num;

		while ( $count < floor( $rating_num ) ) {
				$html .= $rating_icons['full_star'];
				$count++;
		}

		if ( $rest > 0 ) {

			$count = 0;

			while ( $count < $rest ) {

				$dec = $rating_num - floor( $rating_num );

				if ( $half_icon ) {

					if ( 0.7 > $dec && 0.3 < $dec && is_float( $rest ) && 0 == $count ) {
						$html .= $rating_icons['half_star'];
					} elseif ( 0.7 <= $dec && is_float( $rest ) && 0 == $count ) {
						$html .= $rating_icons['full_star'];
					} else {
						$html .= $rating_icons['empty_star'];
					}
				} else {

					if ( $dec >= 0.6 && is_float( $rest ) && 0 == $count ) {
						$html .= $rating_icons['full_star'];
					} else {
						$html .= $rating_icons['empty_star'];
					}
				}

				$count++;
			}
		}

		$html .= '</div>';
		$html .= '<!--/.rating-->';

		if ( in_array( 'rating_num', $atts ) ) {
			$html .= '</div>';
			$html .= '<!--/. review -rating-->';
		}
	}

	return apply_filters( 'poka_affiliate_rating_html', $html );
}
