What is the recommended approach to include a parameter for a custom provider in the openapi spec?

[dschneider-wxs]

I would like to include method as a optional parameter when using XarrayEDRProvider, but this parameter doesn't make sense for general EDR, ie i probably don't want to add it to api/environmental_data_retrieval.py. However, this is where the openapi spec is built from so is there any other way besides patching the generated openapi yml file to include a custom parameter ?
