• I need to configure the HCI_UART project to support DTM testing, but I cannot enable the configuration parameters when I configure it.  The diagram below.  

• How to configure to enable the gray option?

Does Zephyr support DTM test directly? - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

I see similar problems with the link above, but I don't know how to configure it.

Hi Derek, 
I'm afraid that the Nordic Softdevice controller doesn't support DTM directly. If you define BT_LL_SW_SPLIT =y (use Zephyr controller instead of Nordic Controller) you will see that the option will be available. 
So for Nordic controller, you would need to use the \nrf\samples\bluetooth\direct_test_mode example that we provided.
