How to disable topic locales in WPB standalone?

[Gray.K]

Hello, guys!
When end user create a website via WPB then appears window there user can choose language for website and type some information about himself.
I want to make available only one language(locale for website).
Is it possible?

or just skip registration form? and use default (config fallback_locale)
Any advice would be appreciated, thanks
