Unable to Specify Primary ENI for alicloud_instance Resource

Terraform Version

$ terraform -v
Terraform v1.9.1
on darwin_arm64
+ provider registry.terraform.io/aliyun/alicloud v1.237.0

Affected Resources

resource "alicloud_instance"
resource "alicloud_network_interface"

Expected Behavior

The provider should allow specifying an existing ENI as the primary network interface when creating an alicloud_instance.

Actual Behavior

Currently, there is no option in the alicloud_instance resource to attach an existing ENI as the primary network interface. While it is possible to add secondary ENIs using the network_interface block, specifying a primary ENI seems unsupported. However, this functionality is available via the AliCloud console.
