How can I set 'in stock' as a default filter on Flex theme?

Hi, I’m using Flex theme on my store. I was wondering if there’s a way to have the availability filter (through faceted filtering) be checked on “in stock” by default. Also if possible, can the availability filter then be hidden so it can only filter by in stock items?

Thank you

Hello @jastin

Can you share your website URL so that I can check and provide you with the solution to enable the filters?
