Local Anvil App Server - Disabling Excess Service(s)?

What I’m trying to do:
Disable extraneous service calls to external services (Youtube, Stripe, GoogleMaps etc.) that are being made upon each new client session instantiation. Is there a way to do this? (Note: This is being done within a local hosting of the Anvil App Server)

What I’ve tried and what’s not working:
Within anvil.yaml, set an empty services list, also rebuilt the app within the Anvil online editor and exported/cloned to see the generated code for reference on appropriate yaml structure, but it seems like no matter which services are explicitly added or removed from the base configuration, there are still calls under-the-hood being made to Google Maps and the like (can be seen when running Chrome Dev Tools or a packet capture software when loading the application’s client page). The calls fail as there are no API keys configured, but I would like to disable those calls altogether.

Code Sample: Very basic stripped-down anvil.yaml.
anvil.yaml:

dependencies: []
services: []
package_name: test-anvil-app
allow_embedding: false
name: TestApp
runtime_options: {version: 2, client_version: '3', server_version: python3-sandbox}
metadata: {}
startup_form: MainForm
db_schema: []
renamed: true
