@doodlemydomain no problem!
The team mentioned that you can use pagination to set a limited amount of posts to show at once and then go to the next page.
Refer to step 7 in this article: https://support.wix.com/en/article/wix-blog-selecting-layouts-for-the-all-posts-feed-and-category-pages
Another option would be to create your own feed using data and connect it to the post collection dataset.
Hope this helps!
