Turn off serial debug output

When compiling for the NRF52_DK target, it automatically claims P0.6 (amongst others) for serial debugging purposes. How do I configure the MBED online compiler as well as MBED-CLI to not claim these pins?

I tried setting NDEBUG in mbed_app.json as below but the compiled application locks up (no printf() statements are used although sprintf() is).

How can debugging be turned off in the online compiler?

{ "macros": [ "NDEBUG=1" ], "target_overrides": { "*": { "platform.stdio-flush-at-exit": false } } }

I haven't tested this, but it looks like the macro DEVICE_SERIAL could be set to 0 and a lot of the stdio serial init stuff will not be done. That might free up the pins.
