I recommend asking at your theme’s support so its developers and support community can help you with this.
I’m sure making three columns like this can be done with the Elementor plugin, this method is more universal for any theme than using settings on a specific template.
Thank you. I managed to get it right: on the dashboard I changed the Blog page from a Posts Page to a static page (one of the per-page menu options), manually added a 3 columns block, and then added “Blog posts” block content. WP automatically filled the columns with a self-arranging stream of existing past blogs. Nice. You can set how many words to show of the blog text before “read more”. It seems to work.
