If you don't have Pi-hole yet, read my blog post to set up Pi-hole, WireGuard, DoT and DoH servers. After setting up Pi-hole, log into Pi-hole admin dashboard, click on 'Lists' item in 'Group Management' section. Then paste the lists given below one by one (with space or comma in between) in the Address text-box and click on 'Add blocklist' button.
