How to disable App Dir?

Upgraded our app from nextjs 12 > 13. I dont want to use app dir. I get this when i launch my app:

- warn You have enabled experimental feature (appDir) in next.config.js.

- warn You have enabled experimental feature (appDir) in next.config.js.

- warn You have enabled experimental feature (appDir) in next.config.js.

- warn You have enabled experimental feature (appDir) in next.config.js.

My next.config.js even has:

  experimental: {
    appDir: false,
  },

  experimental: {
    appDir: false,
  },

  experimental: {
    appDir: false,
  },

  experimental: {
    appDir: false,
  },
