nRF53: net core image with BLE controller and Radio Test functionality

Question

Hi. 
 I would like to build a FW image for the nRF5340 net core which includes the two mode BLE controller part and Radio Test (like in the Radio Test sample). These two modes should only run mutual exclusive and there should be a possibility to switch between the modes via trigger from the application running on the app core. Also the configuration of the Radio Test should be possible from the application. 
 1) Is it possible to build such an net core image? And if yes, how would I do it with the nRF Connect SDK? 
 2) What is the easiest way to control the Radio Test from the application running on the app core? 
 
 Thanks, 
 Benno

Seems like there is no direct bt_disable function . Looking at the sample code written here , and looking at the nordic implementation of zephyr\soc\arm
ordic_nrf
rf53\power.c, the only way to disable bt is now to turn off your platform. 
 In your case, this might be also helpful, if you write to flash some data before shutting down. On reboot, based on the data written, your application can decide if it initializes bt or the radio test.
