It doesn’t really help. The ISP needs to route you somewhere to get the data, so they’ll need to know who you want to talk to. Even if they don’t see the DNS name (like if you used a third party DNS server) they can still associate the IP address with someone.
There’s things like TOR and VPNs that can route your information through other third parties first, but that impacts performance pretty significantly.
