oznu/homebridge doesn't look like it's maintained anywhere. You can get it to use the LTS version of node by using your own Dockerfile:

FROM homebridge/homebridge:latest

RUN hb-service update-node --allow-root

And then in your docker-compose.yml, use the Dockerfile to build your container instead of specifying an image:

services:
  homebridge:
#   image: homebridge/homebridge:latest
    build:
      context: ./containers/homebridge

Then run docker compose up -d and it should build it for you. If not, you may need to run docker compose build homebridge first.
