How to disable OpenTelemetry?

[Maypher]

I have setup registry as a service in docker compose and I'm running it behind NGINX. When starting up the containers I see in the logs that the registry service it trying to POST to the following url

time="2025-04-05T21:30:19.750432763Z" level=error msg="traces export: Post \"https://localhost:4318/v1/traces\": dial tcp [::1]:4318: connect: connection refused" environment=development go.version=go1.23.7 instance.id=421aa581-63d0-4951-86fe-2505d846c6bd service=registry version=3.0.0

This seems to be some telemetry related functions. However, I don't have any telemetry enable and since I'm running it behind a proxy localhost doesn't really work. Nowhere in the docs does it say anything regarding this. How can I disable it?

Found that according to this issue setting OTEL_TRACES_EXPORTER=none removes the error and OTEL_SDK_DISABLED=true completly disables telemetry.

I feel this should be set to false by default and be configurable by the user but that's how I fixed it.
