There is not a way to customize 404 page in the Theme Options but if you want you can customize 404.php file in the wp-content/themes/kalium/ area.
P.S: Please be aware as by doing customization if something happens like miss-editing files the responsibility is yours and we won't support you on finding the problem, as we are only guiding you how to get the results you need.
