Using environment variable for volume name in docker compose

I am using docker compose version 3.3 and want to use environment variable to define the volume name. I looked at a related question, but that seems to be quite old. With long syntax supported in 3.2, is there a way to achieve that? Here is what I tried in my docker compose file:

version: '3.3'
services:
  target:
    image: "my-registry/my-image:${IMAGE_TAG}"
    volumes:
        - type: volume
          source: ${VOLUME_NAME}
          target: /data
    ports:
     - "${TOMCAT_PORT}:8080"

volumes:
  ${VOLUME_NAME}:

Obviously this syntax does not work as volume name is not substituted in the keys and throws the following error:

volumes value Additional properties are not allowed (’${VOLUME_NAME}’ was unexpected)

Any help will be much appreciated.
