Custom setting page with filamentphp

I'm attempting to set up the edit page as the primary view for a filamentphp resource, specifically for managing page settings. These settings will consist of a single data row, and I want to restrict it to only being editable, with no option to create new rows or delete the existing one. Despite my efforts to find a solution, I haven't been able to. I'm open to any pointers, workarounds, or alternative approaches that could help me achieve this. Thanks for your assistance!
