Deploying website on Vercel with Route53 subdomain

I am trying to deploy my Next.js web app on Vercel with Route53. But I am already using my root domain with main service which is example.com.

I used to deploy with subdomin inside of example.com hosted zone, which is subdomain.example.com.
But I had to add server, cdn, and other 2nd level subdomain like server.subdomain.example.com. So I created a new hosted zone for subdomain.example.com on Route53 and connected with root domain.

So I am trying to add subdomin.example.com on Vercel, but if I add this domain to Vercel project settings, they only get root domain current nameservers.

Is there anyway to add Route53 hosted zone domain to Vercel?
