How to Use Packer to automate and Remove vNIC from import image OVAs?

The team reported issues during the import of the OVA images. We believe this is due to an invalid NIC port group on the base and registry images.

We believe the solution is to modify the NIC with the public port group (included in the config.yaml) during the import process.

The consensus is now that the VMs need to have the vNIC removed prior to export.

Acceptance criteria: An addition to the da-base-image and da-registry image which uses Packer will automatically remove the vnic at the end of provisioning.

Can anyone have experience or can guide to achieve this issue?
