CX as Code: Terraform plan fails on imported custom attributes

Trying to export our full org config for disaster recovery using genesyscloud provider. The export script runs, but terraform plan immediately shows diffs on custom attributes.

# genesyscloud_routing_queue.test
~ custom_attributes = {
 ~ "trace_id" = "otel-span-123" -> (known after apply)
}

The values are being treated as computed instead of static. Is there a way to force the export to treat these as fixed values? Or am I missing a flag in the exporter?
