Building images using OVA + seed.iso

I’m looking at automating the build of Amazon Linux 2 images using Packer. Amazon provides an OVA file and an associated mandatory seed.iso as described in the documentation.

Is this workflow supported by any of Packer’s builders? I see we can export to OVA/OVF but don’t see any way to register a VM from an existing one within any of the VMware builders.

Thanks for any guidance.
