Site Recovery with DES enabled on the VM

I am trying to do a Site Recovery with Terraform. My primary virtual machine has DES (Disk Encryption Set) enabled. But in the Site Recovery module I can’t set DES for the target VM (there is missing an argument like “target_disk_encryption_set_id”). In the Azure Portal I can do this, but I can’t with Terraform.
If I try to do Site Recovery but with the machine without DES - then this is working.

Is this a miss in the Site Recovery configuration in Terraform or intended action?
