How to disable automatic switching to a second network card?

Question

network hardware

Reformulated the description of the problem.
Windows 10.
There are two networks:
1) built-in network adapter (metric 35)
2) smartphone in USB modem mode (metric 75)
Windows uses the built-in network by default, as I need.
The problem is that if you lose connection with the Internet on the built-in - Windows immediately switches to the USB modem. How to make sure this doesn't happen?
Ps Disable is not an option: the USB modem is used in the virtual machine (network bridge -> usb modem). With the help of USB forwarding, the virtual machine can only see the smartphone, but not the modem.

Answer 1

Set the default gateway handles for the network so that it has priority
In Windows, I don’t know how to google
Ip route default gateway "ip gateway"
Something like this

Answer 2

disable the modem in the manager or its network connection on the host, forward the USB to the virtual machine and let the Internet give itself to itself?

Answer 3

Google network card connections via powershell
