Is there a command to undo git flow init?

After git flow init, how to remove git flow model?
Even, I removed related config from .git/config file.
$ git flow init
# force reset
$ git flow init -f
Already remove below content from .git/config file.
[gitflow "branch"]
master = master
develop = develop
[gitflow "prefix"]
feature = feature/
release = release/
hotfix = hotfix/
support = support/
versiontag =
Thanks.
