Circleci.yml empty dependencies override run default commands

Build Environment

I use a circleci.yml file to configure a CircleCI builds for iOS project

The “dependencies” section run by default “Fetch Cocoapods Repo” from a S3 server, which takes almost 3 minutes.

I want to disable this default command for this section with following definition:

dependencies:
pre:
- gem update fastlane
- fastlane --version
override:
cache_directories:
- "~/.cocoapods"
compile:
override:
- fastlane scan
test:
override:

The problem is that the section “dependencies”: with “override” keyword run a default command “Fetch Cocoapods Repo”.

My question is: To avoid running default commands under a section, Is it enough to add keyword “override”?
