Although it is highly advisable to enable ESLint at all times, if you do not want ESLint to run during next build, you can set the eslint.ignoreDuringBuilds option in next.config.js to true like below:
import type { NextConfig } from 'next'
 
const nextConfig: NextConfig = {
  eslint: {
    // Warning: This allows production builds to successfully complete even if
    // your project has ESLint errors.
    ignoreDuringBuilds: true,
  },
}
 
export default nextConfig
