I just saw that option on Summit app, thanks
Edit: after changing the feed settings to mark post I scroll by as read, it is still showed in my feed.
There is a floating action button with three dots, tap on that and then enable "hide read"
Lastly, Marking a post as read while it is scroll by i not ideal and I see it as a work around.
It would be better if there was a different metric like viewed or "scrolled by"
