Customize datetime select tag

How to customize the following liveview tag to use 24H time format instead of using (PM, AM)?

<.input field={@form[:scheduled_at]} type="datetime-local" label="Scheduled at" />

The input component just renders a native datetime-local input. It’s up to the browser which format is used. See <input type="datetime-local"> - HTML: HyperText Markup Language | MDN.
