@marcelovani could you provide an example config with nested values to test, please

[marcelovani]

To be honest I don't remember the use case.

Maybe something like https://git.drupalcode.org/project/drupal/raw/8.8.x/core/modules/image/config/install/image.style.large.yml

langcode: en
status: true
dependencies: {  }
name: large
label: 'Large (480×480)'
effects:
  ddd73aa7-4bd6-4c85-b600-bdf2b1628d1d:
    uuid: ddd73aa7-4bd6-4c85-b600-bdf2b1628d1d
    id: image_scale
    weight: 0
    data:
      width: 480
      height: 480
      upscale: false

How can I override effects.data.width

Maybe it is possible, I don't know, its been a while.
