have you read and applied all described in https://codex.ww.wp.xz.cn/Comments_in_WordPress ?
in extreme, create a child theme, and edit loop.php in the child theme; locate this section near the bottom of that file (shown after the edits), and change it to this:
<?php elseif (is_page()) : ?>
<?php while ( have_posts() ) : the_post();
get_template_part( 'template-parts/content', 'page' );
endwhile; ?>
<?php endif; ?>
Thank you, I wanted to change it without programation course 😉
I found a plugin! 🙂
Good morning Cocolina….I was about to suggest a plugin for this but it sounds like you got one already 🙂
Is it safe to set this topic as resolved?
As a side note, for pages, you can also open up each page and disable comments on a per page basis.
