A Raspberry Pi 3b is adequate to run PiHole to do the job, or implementing AdGuard DNS.
However, these require a little skill and knowledge to implement.
Consumer routers aren’t built to do the job.
Comment on Self-Hosting a DNS Sinkhole is really important

I only know the basics of networking, so I’ve been wondering why this “DNS-sinkhole” fubctionality can’t simply be implemented directly in private routers as a simple blocklist instead of adding a new device to your network. Do routers not support this for technical or security reasons?

Routers are usually hardware level optimized for throughput, filtering is inherently computationally expensive compared to routing, especially if you have to keep up multi-gigabit throughput
You could totally do it at the router, it would just become a more expensive piece of hardware and most people choose to cheap out
