AdGuard is not a DNS blocker
It's both a browser extension and a DNS filter.
https://adguard-dns.io/kb/general/dns-filtering/#how-does-dns-filtering-work
Edit: It seems the apps can act as a VPN to filter traffic.
You where talking about "system wide AdGuard", which is not the browser addon, but an app that uses DNS blocking, be it by either letting people set DNS servers manually, or automatically through VPN. Their VPN does not break TLS connection by inserting custom certificates and MITM proxies, so they cannot read/modifiy content.
It might be possible to use TLS breaking proxies for systemwide ad blocking, but even that wouldn't help, because nowadays a lot of content and ads are loaded dynamically via javascript. So a browser is required to filter ads.
Maybe you are looking for SpamGuard, TrojanGuard, VirusGuard, MalwareGuard, SpywareGuard, RansomWareGuard, etc. instead.
