Tethering via RNDIS instead of Wi-Fi hotspot?

[brlin-tw]

Hello, I would like to ask whether I can start a proxy service without launching the Wi-Fi hotspot?

I'm currently using the following configuration:

• "Bind Proxy to All Interfaces" option toggled
• Connect the phone to PC, then enabled USB tethering
• Use the gateway address of USB tethering as the proxy server host address

While it works as expected, I do not want the Wi-Fi radio also powered without any purpose and unnecessarily generates heat, can I switch it off or there's another application that is more fit for my usecase?

Thanks in advance!
