DreamFactory how to disable wrapper "resource" in docker container

I'm using DreamFactory REST API in a Docker container and I need to disable wrapper "resource" in payload. How can I achieve this?

I have replaced the following in all of these four files:

opt/bitnami/dreamfactory/.env-distopt/bitnami/dreamfactory/vendor/dreamfactory/df-core/config/df.phpopt/bitnami/dreamfactory/installer.shbitnami/dreamfactory/.envDF_ALWAYS_WRAP_RESOURCES=true

with:

DF_ALWAYS_WRAP_RESOURCES=false

but this doesn't fix my problem.
