Please consider this as an enhancement.

CNAME cloaking is in place to bypass tracking list. Please do go through this article - https://medium.com/nextdns/cname-cloaking-the-dangerous-disguise-of-third-party-trackers-195205dc522a

uBlock Origin Firefox extension is configuring a DNS lookup to prevent such tracking. See;
uBlockOrigin/uBlock-issues#780
gorhill/uBlock@3a564c1

Is AdGuard protected from such bypass procedures? Is using AdGuard DoH service sufficient to stop such tracking?

Closing this as I found a AdGuard blog post and twitter entry which mentions that AdGuard DNS blocks CNAME cloaking.
