If I understood you correctly, this is done by extending this file (brief view), i.e. in fact you need to customize all the elements for summary.

Thanks! That's what I thought, well changing the entire layout of the summary is kinda complicated. Sure, I can change the summary but it will only change one item. I want to change the design to a three columns grid and use cards (Tailwindcss)

You may create a new component \views\default\page\components\grid.php and call it via elgg_view_entity_list() in your custom layout.
