as read before I found, that there is no way to remotely install the apk.
But: can I install it locally, i.e: via usb ?
If so: where do I get the apk from ?
You can only update Kiosk Browser remotely if using Remote management with a Samsung device: https://kioskbrowser.userecho.com/topics/1280-update-manager/
