if you don’t want to update to macOS Catalina, and you don’t want Software Update bugging you about it, just run this in your terminal:
sudo softwareupdate --ignore "macOS Catalina"
reverse it > Yes, you just have to run sudo softwareupdate --reset-ignored

so write a small cron job to kill the red badge.
