Please someone help me to configure the dns manager

Hello, I am very noob on this subject and I need help, I have 1 VPS with HestiaCP installed on this VPS has 2 External IPs, I want to put my domain example: lala.com on the hestia that is in another domain provider (no is the same as I hired the vps) how do I configure ns1 and ns2 to be able to manage the dns of my domain in hestiacp using 2 IPs even though it is only 1 VPS, 1 IP for ns1 and another IP for ns2?

In summary I am not able to manage the dns of my domain using hestia.
