No, the second option is not selected in linux-image-4.16.0-2-amd64 [5].

```
#
# Display Engine Configuration
#
CONFIG_DRM_AMD_DC=y
# CONFIG_DRM_AMD_DC_PRE_VEGA is not set
# CONFIG_DRM_AMD_DC_FBC is not set
# CONFIG_DRM_AMD_DC_DCN1_0 is not set
# CONFIG_DEBUG_KERNEL_DC is not set
```

It’s selected in linux-image-4.17.0-1 [6]. That version is not yet in 
Debian Buster/testing.

I wonder, if in the future the Linux kernel could give feedback to the 
user if options are unselected.


Kind regards,

Paul
