Hi!
Yes, it is possible. On the General Options -> Behavior panel you can set the number of characters to trigger the search. If you set it to 0, it will work without typing in anything: https://i.imgur.com/pWDeJ0h.png
There is also an option to hide the whole search bar if you don’t want to use it: https://wp-dreams.com/knowledge-base/how-to-use-filters-only-and-hide-the-search-bar/
