Replace custom node driver

I deployed a cluster with a custom node driver and want to update it to the newest version, which provides more features →

https://github.com/JonasProgrammer/docker-machine-driver-hetzner/releases/download/3.2.0/docker-machine-driver-hetzner_3.2.0_linux_amd64.tar.gz

But when I try to deploy a new node with the new driver, it looks like Rancher uses the old driver, which does not provide the new features. So it ended up in an error state:

“Flag provided but not defined: -hetzner-networks; Timeout waiting for ssh key”

Is there a way to tell the cluster to use the new driver?
