Is it possible to use different image depending on the platform?

[voidcontext]

What would be the best approach to use different image for a step based in the platform? Let's say some-image on linux/amd64 and aarch64/some-image when it's linux/arm64.

Actually I think I found a solution, it might not be the best but it seems it works well:

matrix:
  include:
    - platform: linux/amd64
      image: some-image
    - platform: linux/aarch64
      image: aarch64/some-image

labels:
  platform: ${platform}

steps:
  release:
    image: ${image}
    settings:
      ...

Why not use a multi-arch image and let docker care about this?
