Temporal scalable HEVC with NVENC

It seems that NVENC has no builtin support for temporal scalable HEVC (SUPPORT_TEMPORAL_SVC=0). We plan to implement it by setting relevant fields in NV_ENC_PIC_PARAMS_HEVC, which requires NVENC to honor TID values when picking reference frames. Is this a supported use case?

NV_ENC_CAPS_NUM_MAX_TEMPORAL_LAYERS Indicates HW support for encoding Temporal layers.
0 : Encoding Temporal layers not supported.
1 : Encoding Temporal layers supported
