DNS configuration for ads sinkhole


I already use MIAB and its DNS as my main DNS.
I was looking at installing a “pi hole” to block ad in my home network…but then I came to think that I do have my own DNS already in MIAB and my internet box already use it as my internal DHCP configuration.

So, does anyone know how would it be possible to configure nsd4 in order to do so ?

Thanks a lot
