How to remove handlers from root logger

Question

I want to set up centralized logging for my quarkus application and found this guide which recommends gelf as a tool to send messages to Logstash.

Enabling the gelf-handler does produce output, however the handler is immediately registered to the root-logger and I want to only specific loggers to log to gelf.

In short: I would something like this in my application.properties

quarkus.log.level=INFO
# This seems to not be possible
# quarkus.log.handlers=console,file
quarkus.log.category."org.acme".level=DEBUG
quarkus.log.category."org.acme".use-parent-handlers=true
quarkus.log.category."org.acme".handlers=gelf

quarkus.log.handler.gelf.enabled=true
quarkus.log.handler.gelf.host=tcp:localhost
quarkus.log.handler.gelf.port=12201

How can I achieve this effect?
