Windows 10 how to change the metric (priority) of the interface?

Question

Computer networks

There is Windows 10. And this Windows 10 no matter how you try to assign a metric manually, it still assigns it itself.
The bottom line is that a 3G modem is inserted into the computer and the Internet should only work through it, a wired network is also connected to the computer. Naturally, while the wire is connected, Windows will strive to get the Internet from it. But from the wire you only need access to the local area, nothing more.
I tried to enter the route manually with a larger metric in PowerShell.
Tried not to enter the route at all.
I tried to enter the route and specify the metric explicitly in the network card settings in the network and sharing center.
I tried to set an indecently large metric for the wired interface.
And still, paradoxically, when the cable is connected, the traffic through the modem stops going.
How to fix it? How to make Windows 10 work only through a 3G modem, regardless of whether the cable is connected or not?

Сетевой адрес           Маска сети      Адрес шлюза       Интерфейс  Метрика
          0.0.0.0          0.0.0.0   100.124.84.198   100.124.84.197    258
          0.0.0.0          0.0.0.0     192.168.47.1    192.168.47.12   2666

Top modem bottom wired interface. As you can see, the wired interface has a very large metric, while the modem has a much smaller one. But traffic still goes through the network card.
Even if in the settings of the network card it will not help to completely erase the gateway ...
