Hello

I want to run samples/bluetooth/ipsp on K64F board.

I understand that if networking is enabled, FRDM_K64F by default uses
Ethernet. So I should modify Kconfig.defconfig to disable Ethernet
and enable Bluetooth.

I add the following to /boards/arm/frdm_k64f/Kconfig.defconfig

What is the proper clean way to disable NET_L2_ETHERNET and ETH_MCUX
and enable Bluetooth ?

The idea of any board defaults is just that - they're the defaults, and
should be overridable by a user. Did you you try to override those
defaults in your prj.conf? If that doesn't work after reasonable effort,
please submit the issue at
https://github.com/zephyrproject-rtos/zephyr/issues/new with detailed
steps and info to reproduce.
