How to use hccl with horovod?

I am trying to run some DL orkload with horovod (one with tensorflow and one with pytorch). Installing horovod with pip build with gloo, mpi and nccl and it uses mpi for collective operations. How can I use hccl for collective ops with horovod?

Horovod is not supported for pytorch. We use DDP for scaling.
