How to turn off graphql playground on production?(nextjs api route)

[sourovch]

Hello I am using graphql-yoga to open a graphql server in my nextjs app with keystonejs. When in production I want to disable the graphql playground. but I am unable to find any way in docs to to this, anyone can help? my code below:

import { createYoga } from "graphql-yoga";
import { keystoneContext } from "@/keystone/context";
import processRequest from "graphql-upload/processRequest.js";
import { getSession } from "@/lib/getSession";

export const config = {
  api: {
    bodyParser: false,
  },
};

export default async function handler(req, res) {
  const contentType = req.headers["content-type"];
  if (contentType?.startsWith("multipart/form-data")) {
    req.body = await processRequest(req, res, { maxFileSize: 5242880 });
  }

  return createYoga({
    multipart: false,
    graphqlEndpoint: "/api/graphql",
    schema: keystoneContext.graphql.schema,
    landingPage: false,
    context: async ({ req, res }) => {
      const session = await getSession(req, res);
      return keystoneContext.withSession(session);
    },
  })(req, res);
}
