This may result in this failing in older sp's if they are still using old installer, but I doubt that they will face the problem as the nvidia repos are already present for released products

Thanks, you are correct, I noticed that autoyast uses the same workaround

autoyast/installation.pm

    elsif (match_has_tag('nvidia-validation-failed')) {
        # nvidia repositories are unstable and really not needed for anything
        record_info("NVIDIA", "NVIDIA repository is broken");
        wait_still_screen { send_key 'alt-o' };
        send_key 'alt-n';
        $num_errors++;
    }
