Locked Filter for items without value

Hello,

On a category menu item, is it possible to set the locked filter for items that do not have a specific value?

For example, I have a checkbox with one option and want to display items that are not checked.

Thank you

no for now you can do for a value only

I was able to add a second value to my checkbox and set the filter as it's intended.

Thanks for the reply
