How to disable telemetry ("metric" parameter)

[DHBytes]

I am self hosting Memos using Docker and I want to disable any telemetry data sent to Memos.
According to the self-hosting documentation, it can be disabled by setting the --metric parameter to false.

This is my docker compose:

version: "3.0"
services:
  memos:
    image: ghcr.io/usememos/memos:latest
    container_name: memos
    volumes:
      - ~/apps/memos/:/var/opt/memos
    ports:
      - 5230:5230
    command:
      - "metric=false"

However, it's being ignored and the logs show that the metric parameter is "true":

---

data: /var/opt/memos
dsn: /var/opt/memos/memos_prod.db
addr: 
port: 5230
mode: prod
driver: sqlite
version: 0.18.1
�
metric: true

Is my docker compose syntax wrong (I am not good at Docker)? How can I disable all telemetry and metrics from being collected? Thanks!

(By the way, data collection should be opt-in not opt-out, especially since Memos site states it is a "privacy-first" service. Come on, guys!)

Ok, I just added the MEMOS_METRIC=false env var to the container as mentioned here.
This should be documented better.

This is already described in the documentation. https://usememos.com/docs/install/self-hosting#parameter-options

I know, but I'm asking for help with the Docker syntax. Where do I add it in the docker compose yaml?
