Any way to disable channel 12/13 on Nokia G-140W-F

My desktop seems to support only US bands. It has TP-Link pci card US version and I found out after lot of trials/driver updates/OS resets as the SSID would randomly show up and connection is unstable many times.

Is there a way to disable the channel 12/13 for the 2.4 ghz WiFi? It's pretty slow if I choose a single channel.

The Airtel guys said that can't be done. So I used the WiFiAnalyzer android app to find channel with least usage and changed my router to that. So now I'm able to use the PC but all other device speed has gone a little down.

Adding details here so that other people searching for issue may find this useful.

PCI card: TP-Link TL-WN881ND 300 Mbps V2.2 (US) (you can get the details from the box)
Issue: The one bought off Amazon.in was US version. This doesn't support Channel 12/13 but my router seems to prefer 13 due to least interference. Not sure if they even sell EU version
Solution: Manually set the channel to something lower (verify with app like WiFiAnalyzer).
