Hello, In Harvester HCI, I currently get VM IPs from the company switch DHCP, but leases expire after some time. I want an internal DHCP inside Harvester (so VMs always get IPs automatically without relying on the switch). Is it possible? If yes, what is the recommended way to configure DHCP for VMs in Harvester?

Yes it is : https://docs.harvesterhci.io/v1.5/advanced/addons/managed-dhcp

Thank you @thousands-advantage-10804 but currently I am using harvester HCI v1.6 and in this managed DHCP is for experimental purpose tried to do this but not able to achieve.

In theory you should be able to setup vm with dhcp on the same vlan.
