Hi @BIGSHOTInt,

I hope you are well today and thank you for your question.

This is actually a plugin territory and not theme.

You can try achieving this using any of the following plugins

https://wordpress.org/plugins/page-specific-menu-items/

https://wordpress.org/plugins/different-menu-in-different-pages/

Or you can consider hiring a developer to develop it for you. You can hire a developer from any freelance site. Shufflehound recommends the developer https://www.upwork.com/freelancers/~011652ffec8865c6d5

Best regards,
