I managed to pin the revision to an older version by setting env var CONAN_REVISIONS_ENABLED=1 and using boost/1.74.0#3b52fbf45879b8b288e59d454d1c4765, if someone has the same issue.

@gummif There’s any way to pin all index revision to not affect the actual state of build of conan for futures changes? This affected our Jenkins build and non-cached builds, we want to prevent it…
