Block/disable SSH for a specified docker container

Hi.

Forgive my bad english, not my first language.

I'm using the docker compose plugin on my OMV.

One of the containers I have is the "code-server" one, with which I can have my own server to run Visual Studio. I've noticed that from the code-server container I can ssh to OMV, something that from a security point of view seems unacceptable to me considering that I'm thinking of exposing that container to the internet using reverse-proxy. I would like to disable/block ssh to OMV only and exclusively for that container.

How could I achieve that using the OMV web interface?

Quote from chente

Is root the user who runs that container?

Yeah, which I find frustrating because I specified in the PUID and PGID variables of linuxserver that they would not use root and instead use another user that I had created specifically for that purpose. Maybe those variables don't decide who runs that container?

services:
  code-server:
    image: lscr.io/linuxserver/code-server:latest
    container_name: code-server
    environment:
      - PUID=1001
      - PGID=100
      - TZ=Europe/Madrid
      - PASSWORD=XXXXXXX #optional
      - HASHED_PASSWORD= #optional
      - SUDO_PASSWORD=XXXXXX #optional
      - SUDO_PASSWORD_HASH= #optional #optional
      - DEFAULT_WORKSPACE=/config/workspace #optional
    volumes:
      - CHANGE_TO_COMPOSE_DATA_PATH/code-server/config:/config
    ports:
      - 8443:8443
    restart: always
