I'm deploying my agent on Cloud Run using get_fast_api_app and defining the agent with LlmAgent.
I need to explicitly set in code the values of some parameters that at the moment users can define instead only with environment variables
The parameters are
GOOGLE_CLOUD_PROJECT
GOOGLE_CLOUD_LOCATION
GOOGLE_GENAI_USE_VERTEXAI
I need this variables to be called differently, so being able to explicitly assign them a value in Python code would be very handy.
