Using GET to manage a EKS hybrid environment (upgrades)

So, we have 16.3.3ee setup using GET in production, but need to upgrade to the latest version 16.3.4. I see that zero downtime upgrades are not possible with a hybrid envrionment and that is ok, however ansible only has a zero_downtime playbook? docs/ · main · / GitLab Environment Toolkit · GitLab

What is the proper procedure for upgrading a hybrid environment with the toolkit? Do I just need to run the whole playbook again (all.yaml?)

Any guidance appreciated.
