It is not clear what you would like to do.
Do you want to hide parameters of a family?
Do you want to control the visibility of a family with a parameter?
Please reply with more specific steps that you are going through, and what exactly you would like to do. A screenshot or short video would also be helpful.

Thanks & Regards
At ths time, I don't believe there is a way to hide parameters from users.
