please add huggingface args in unstructured.partition.xx functions

I use os.environ to make unstructured know that i need use diffrent huggingface endpoint ,but it didn't work.
my code is these:

os.environ["HF_ENDPOINT"] = "https://hf-mirror.com"
os.environ["HF_HOME"] = "/workspace/huggingface_cache_dir"
os.environ["HF_HUB_DOWNLOAD_TIMEOUT"] = "300"
os.environ["HF_HUB_OFFLINE"] = "0"

elements = partition_image(
    filename="test_img.png",
    languages=["eng","chi_sim"],
    text_as_text=False,
    include_metadata=True,
)

It still going to huggingface to download models
but my network can't view the official huggingface web site

is there someone tell me how to make it right?
thanks a lot

Start with the partition_image example and trace the unstructured.partition.xx functions named in the request, then check how their model downloads currently receive configuration. Confirm the desired Hugging Face arguments and update the relevant function interfaces consistently; done means callers can control endpoint, cache, and timeout behavior without relying only on environment variables, with tests covering the new arguments.
