Is there a folder I can place on Photos to keep private on my iPhone 13?

Hi. I know people appreciate the organization of people & places & pets; however, I prefer to avoid this. Is there a folder I can place what I want to keep private on my iphone 13?

Particularly for any children in the photos. I am not labeling minors. And in the law, minors have confidentiality so why not on the iphone too?
