Hello, i have a forum topic with a youtube video embedded in every post and so the page takes too long to load because the number of comments per page for the "forum" content type is 50.
I would like to change it to 10 for this topic (node) only and leave it to 50 for all other forum topics.

Any suggestion about to achieve this? Is there some variable that i can preprocess?
Creating a variant with page manager and panels is not an option for other reasons.

Thanks.
