Disabling NextJs experimental app directory

I’m working on a real life project and decided to test the new App directory that comes with the Next js 13 version, I noticed some glitches like my images and fonts not loading properly, etc. I would like to stop using the experimental app Dir.
Is there a way to opt out of the experimental app directory locally without having to reinstall next-app?, please I’m new to Next js.

Here is my next.config.js

/** @type {import('next').NextConfig} */
const path = require("path");

const nextConfig = {
  experimental: {
    appDir: true,
  },
  sassOptions: {
    includePaths: [path.join(__dirname, "styles")],
  },
  reactStrictMode: true,
  images: {
    loader: "akamai",
    path: "/",
  },
};

module.exports = nextConfig;

Whenever I put the appDir as false, I get the following error

Error: > The `app` directory is experimental. To enable, add `appDir: true` to your `next.config.js` configuration under `experimental`. See https://nextjs.org/docs/messages/experimental-app-dir-config
