Problemas con DNS

Hola, tengo mi sitio web alojado en Heliohost.org, alli migre a un hosting mas amplio y ahora me dicen que elimine los DNS de Cloudflare y coloque los de ellos para que el proceso culmine. El problema que tengo es que no encuentro por ninguna parte la forma de colocar los DNS de heliohost ya que cloudflare me da sus DNS sin oportunidad de editarlos o cambiarlos, necesito cambiarlos a estos:
ns1.heliohost.org
ns2.heliohost.org
alguien podria ayudarme?

This is done at your domain registrar, where you pay for your domain name. You did not post your domain name, so we can not look it up. Hopefully you can log into your registrar account and update the name servers.

my domain name is: radioretroperu.com
my registrar is Cloudflare this is where I have my domain registered.

Domains registered at Cloudflare have to use Cloudflare name servers. If you don’t want to use Cloudflare, you need to transfer your registration to another registrar.

thanks, i’ve already fixed it. thanks for your support. Closed topic.
