No UVM: A30 MIG-backed vGPU

Is UVM for MIG-backed vGPUs working? I added “enable_uvm=1” to my vgpu_param’s and can’t get it working. I get an “Operation not supported” error string when using cudaMallocManaged. Other vgpu_params, like “enable_profiling=1”, work perfectly fine.
I am using the latest vGPU (14.x) version, KVM, Ubuntu 20.04, A30, MIG-backed, and GPU pass-through.
Thanks.
