Additional Information
is there any hope for AdGuardHome to have new feature for blocks all type of VPN connection to not bypass it in home LAN if i have up and running AdGuardHome in my home and try to bypass it using VPN application is there any way to broken VPN links through AdGuardHome as it DNS server
What a DNS server can do is very limited, maybe you can block the VPN service provider's domains, such as ||engage.cloudflareclient.com^ for Cloudflare WARP, but the users can easily bypass your blocking by using other DNS servers. So, this isn't about AdGuardHome, you really need other solutions instead of DNS server.
You really need a firewall for this - as fernvenue stated, DNS is easily bypassed by those who have even a moderate understanding of IP networks. And while bypassing DNS can of course be thwarted, doing so requires a firewall.
