Does AV1 on Ada architecture support delta qp map?

Hi team, for NVENC, we could add delta qp map to spatially adjust qp values for macro-blocks in HEVC (h.265) mode. Does anyone know if this delta qp map is supported in AV1 mode? I read the paper about AV1 which seems supporting this mechanism, but not sure if NVENC on Ada supports it or not.
