Hey @charlesatftl,
We have already released DLCs for transformers 4.11 with PT1.9. Sadly, there is a bug in the python-sdk, so the image_uri cannot be generated automatically. Issue: aws/sagemaker-python-sdk#2700 5
Until this bug i solved you can use the image_uri directly.
# create Hugging Face Model Class
huggingface_model = HuggingFaceModel(
    #transformers_version='4.11',
    #pytorch_version='1.9',
    #py_version='py38',
    image_uri="763104351884.dkr.ecr.us-east-1.amazonaws.com/huggingface-pytorch-inference:1.9.0-transformers4.11.0-gpu-py38-cu111-ubuntu20.04",
