Does tensorrt support dynamic quantization?

Description

I used quantize_dynamic from onnxruntime to quantize onnx model. But it could not convert to tensorrt plan.
error is Non-zero zero point is not supported. Do you know how to fix it?

Steps To Reproduce

Commands or scripts:

Have you tried the latest release?:

Attach the captured .json and .bin files from TensorRT's API Capture tool if you're on an x86_64 Unix system

Can this model run on other frameworks? For example run ONNX model with ONNXRuntime (polygraphy run <model.onnx> --onnxrt):

Start by reproducing the Python quantize_dynamic flow shown in the issue and inspect TensorRT's ONNX importer handling of the DequantizeLinear node and its non-zero zero point. The issue is resolved when dynamic quantization support or its limitations are established, with the required quantization settings or a documented explanation of the failure.
