Question

There is a way to add a block list and use wrap client like adblocker?

The list would be oisd.nl

Answer

Cloudflare themselves decide, to my knowledge, which sites will be blocked by WARP, so they run their own blocklist.

A cloud-bound service with the functionality you are looking for would be NextDNS, they have native integrations for many popular blocklists.
