DNS Server Cache in Cyberpanel?

Sorry I’m beginner and want to ask about DNS:

  1. I s there menu to set TTL DNS Cache in Cyberpanel?
  2. To configure the TTL DNS Cache, is it in server side (web server) or client side (client computer)?
  3. In my domain registrar they have DNS Server and in Cyberpanel also has DNS Server. Should I configure both DNS with the same configuration? Or I should only configure one DNS (either in domain registrar or Cyberpanel)? And lets say I configure A record in DNS Server in my domain registrar to a different IP with A record IP in DNS Cyberpanel, which one is used by the internet?
