How to set the threshold value in an exported model in anomalib 2.0

[haimat]

I have trained a ReverseDistillation model in anomalib 2.0.
Then I exported it to ONNX format like this:

engine.export(model=model, export_type=ExportType.ONNX, export_root=".", ckpt_path="/path/to/last.ckpt")

As I learned from the anomalib post-processing docs the threshold value is baked into the model, so how can we dynamically change that after export? In other words, if I want the exported model to behave more or less strict during inference, how to do so?
