Autogen setting ca bundle / verify

Does anyone know if it’s possible to set the ca bundle / http client verify for autogen’s group chat? I know I can set it with

    os.environ["SSL_CERT_FILE"] = ca_bundle_path
    os.environ["REQUESTS_CA_BUNDLE"] = ca_bundle_path

but I’d much rather only set it such that calls to openai will use the CA bundle path I provide.
