Parental Control APP for Amazon Tablet?

Hello. I have an Amazon Fire 10 Generation 9 tablet with OS 7.3.2.7. with the Parental Control features turned on. It’s a long story, but I would rather not also use the Child Profile(Amazon Kids) function of the tablet. However, I’d like to limit the violence, obscenity, an mature content that can be accessed by children on the web, in games, etc.. Can anyone recommend an app that can handle this? Thank you. John
