Moving SSL key to redundant gateway

I’ve automated SSL Deployment using Let’s Encrypt and Certify the Web on my primary gateway, but I can’t seem to find a way to easily automate copying the SSL Cert to the redundant gateway.

I thought maybe I could script it in Ignition but don’t see an easy way.

Does anyone know of a good way to copy the SSL Cert? (I’m using Windows Server 2019)
