Change default decimal seperator

Hi, I noticed that the decimal separator is not always the same in my app. e.g. for grids it is displayed correctly with a dot, but for numberfields it renders a comma. Is there any way to change the separator to a dot consistently throughout the app?

I read that this can also depend on the browser settings. If so, is it not possible to override them in Vaadin?

Does anyone have an idea? Already looked at the doc on I18NProvider, but I don’t know if this will help me
