For this, in nextjs apps you can always use next-seo, so in your code:

import React from 'react'
import { NextSeo } from 'next-seo'
...

<!-- in your component -->

const { title } = props

return (
    <div>
      {title && (
        <NextSeo
          title={`Here goes your custom title ${title}`}
          description={description}
        />
      )}

    </div>  
)

So in builder, just pass the title as a props to your custom component, then you will be able to customize it in the editor
