[Question] [python-fastapi] How to set _spec_property_naming = True via command line

Created by: puneetugru

Description

We have a requirement where we would like to generate only the model files, inheriting from pydantic BaseModel.

Hence, we would like to use python-fastapi as the generator type.

But, we would also like the openapi-generator to NOT generate model names with snake_case, but rather with camelCase.

As per #10458 (closed) the support exists as part of the python-experimental generator.

But, the same is failing due to #11518 (closed)

But, is there a way to set _spec_property_naming = True as a command-line argument with the generator set as python-fastapi?
