Need help changing homepage to scrolling not blog posts!

I am building myself a website and on the homepage it has the blog posts but instead I want the scrollable features with the panels.

My page: https://issyhearn.com

What I want it to look like: https://wordpress.com/themes/affinity/ (section where it shows the “scrollable” feature.

(Don’t have premium account)

Seems simple but I can’t figure out how to get it sorted. Any help would be amazing!
