For anyone using Hurricane Electric's dynamic DNS records in https://dns.he.net/, here is an ACME DNS API plugin script for PVE:
https://github.com/markkuleinio/pve-acme-he-ddns
If I have understood it correctly, Proxmox will update their own proxmox-acme repo from acme.sh repo in GitHub, so if/when the PR gets merged at some point later, then the HE DDNS API script will be readily available in PVE installations without manual actions. But meanwhile, this manually installed script works nicely with my own PVE nodes.
