Currently there is no option to disable specific steps. You have to delete the steps and re-add it if you want it again. All settings needs to be done again.
Use case / for what or how I would use it
Initial upload of aab or apk file is not possible by “play deploy step” it needs to be done manually. so we want to deactivate it for the first builds and activate it again, after play store entry is available.
i can imagine that there are some other use cases…
