Specifying local DNS server

On my network I have my own DNS server featuring some nice parental controls. I can specify this server as primary DNS server in the DHCP settings (Domain Name Server (DNS) Address). But Orbi will then pass on the router's ip as DNS server to DHCP clients and subsequently all DNS requests seems to origin from this router address from the DNS server's point of view.

Is it possible in the setup not to act as DNS proxy but rather pass on the custom DNS server specified to connecting DHCP clients?
