uBlock Origin can block anti-blocker mechanisms just fine. If you find one site not covered by uBO, it's just a matter of reporting it to filter list maintainers, they will fix it: https://github.com/uBlockOrigin/uAssets/issues?q=is%3Aissue+is%3Aclosed
Filter list maintainers fix that sort of issues many times per day (all on their free time), as sites change constantly and new sites are reported, see https://github.com/uBlockOrigin/uAssets/commits/master
For your information, know that using another similarly purposed content blocker along uBO will likely prevent uBO from working as intended, they will negatively interfere with uBO, see https://twitter.com/gorhill/status/1033706103782170625
