How to disable Matek F405-WTE onboard receiver

This fc has an onboard elrs receiver but I dislike it. Is there any way to turn it off so that it doesn’t jam another receiver that I use?

I don’t know about disabling it but you could flash the radio to WiFi telemetry instead of ELRS.

But Wifi also use 2.4GHz, it may jam my 2.4G receiver

Maybe just don’t connect ERx and ETx? You could probably even leave the antennas off since it shouldn’t try to transmit anything in this state.

I think I will just pinch the boot button with a clip so that the receiver will always enter boot loader.
