You cannot, or at least shouldn't be able to. All HMs were replaced with Key Items for the current version. As the page says, you obtain the Snorkle in Sario Town, which allows you to go underwater in Rainbow Reef. So I guess you could say you get access to Dive after the 6th gym. Make sure to pick up the Shiny Charm as well.
