Hide unnecessary fields

I met a warning in google webmaster
”
Warning The “priceValidUntil” field is missing
Warning The “aggregateRating” field is missing
Warning “availability” field is missing
Warning The “brand” field is missing
Warning The “url” field is missing
Warning The “sku” field is missing”
I want to hide unnecessary fields in: wp-product-review\includes\functions.php

if ( ! function_exists( 'wppr_schema_data_types_allowed_brand' ) ) {
	add_filter( 'wppr_schema_data_types_allowed_for_Product', 'wppr_schema_data_types_allowed_brand', 10, 1 );
	add_filter( 'wppr_schema_data_types_allowed_for_IndividualProduct', 'wppr_schema_data_types_allowed_brand', 10, 1 );
	add_filter( 'wppr_schema_data_types_allowed_for_ProductModel', 'wppr_schema_data_types_allowed_brand', 10, 1 );
	add_filter( 'wppr_schema_data_types_allowed_for_SomeProducts', 'wppr_schema_data_types_allowed_brand', 10, 1 );
	add_filter( 'wppr_schema_data_types_allowed_for_Vehicle', 'wppr_schema_data_types_allowed_brand', 10, 1 );

	/**
	 * IndividualProduct, Product, ProductModel, SomeProducts, Vehicle need the Brand field.
	 */
	function wppr_schema_data_types_allowed_brand( $types ) {
		$types[] = 'schema:Brand';
		return $types;
	}
}

I don’t want to show them how?
