@loobyloo_2 a little clarification needed. What is your final goal with this question, just hide the checkbox, or avoid new users to receive messages on your site?
If it's just hide the checkbox, you need to override the fallback comment form in your skin. In plain english, copy the file
/skins_fallback_v6/_item_comment_form.inc.php into your skin directory and delete the section between lines 424 and 428 (it may vary) of the new file: https://github.com/b2evolution/b2evolution/blob/release/6.8.x/skins_fallback_v6/_item_comment_form.inc.php#L424
