Update NCCL timeout

I want to update the nccl timeout from 30 minutes to 5 minutes after step 1

        torch.distributed.init_process_group(
            backend="nccl",
            world_size=world_size,
            rank=rank,
            timeout=timedelta(minutes=30),  # 30 is the default but be explicit
        )

Is that possible somehow? Maybe there is an os.environ trick?
