Support for HF by the inference engine when using DFlash

[lixinqi7]

if getattr(args, "inference_engine_type", "hf") != "sgl":
raise NotImplementedError("DFlash currently supports only inference_engine_type='sgl'.")

Currently, DFlash only supports SGlang as the inference engine. Can I simply ignore this error and forcibly use HF as the inference engine?
