In Gerrit patchsets, comments tend to fall into three categories: 1) the user uploading new patchsets, 2) jenkins verifying the patchset, 3) actual code review comments.
This leads to quite a mind-boggling interface. Example lengthy patch (gerrit 27022):
As a code reviewer, only the highlighted comments would be of any interest.
Recent versions of gerrit support hiding non-comments (1) and also allow hiding CI comments (2) as long as they are tagged (this requires setting a tag field when submitting the change; see docs). The Zuul code creating the review comments would have to be updated to support this.
