Use multiple DNS services simultaneously? Like AdGuard + DNSCloak

I would like to use DNS to increase privacy. There is one question there. Should I run multiple DNS at the same time? For example, you can run Ad Guard Plus and DNSCloak apps on iOS at the same time. please tell me! ! Also, please tell us the recommended combinations! I want to hear about iOS and Linux.

DNS isn’t a privacy feature but necessary to translate human-readable domain names into machine-readable IP addresses.
