Win11 IoT networking issue with ethernet vs / cellular

Hello. So I have these windows 11 IoT Enterprise LTSC devices with built in LTE modems. Internet access is provided by the LTE connection. Frustratingly, as soon as windows 'detects' an ethernet link, internet connectivity goes down. (The ethernet connection has no internet connectivity itself, just a few locally networked devices) The LTE modem stays connected and online, but windows refuses to use it. Ping -t goes from working to "transmit failed. General failure." as soon as ethernet is detected. The same behavior happens even after setting the interface metric of the LTE modem to the lowest value. Any thoughts on getting Win11 IoT to use the only active internet connection no matter what's plugged in via ethernet?

Any help greatly appreciated
