Security Question - on Yes/No field, option for "Is not yes" instead of "is No"

I’d doing a lookup on someone’s permissions in our database and I’m referencing a yes/no field in our database. Is there a way for me set a lookup value for “Is not yes” instead of saying “is no” which matters if someone were to have a null value for this field.

Not a big deal, but a good practice for security reasons. Curious if there’s a good solution in Bubble?

Can you test to see if “is no” matches null as well as no?
