Try to create a staging site, and on it please Install the theme and then simply create 2 unique and totally different products on it, and then check the result.
Otherwise, you can try with any third-party plugin for SEO as well, like the Yoast SEO or RankMath SEO plugin, if anyone provides the functionality to solve your issue, you can concern with the plugin Authors first.
