I come back to the previous post (Orange Pi 3 : Armbian-config system/Default Install desktop doesn't work).
Functionality armbian-config System/Default (Install desktop with browser and extras) works with Armbian_19.11.6_Orangepi3_stretch_current_5.4.7.img, but does not work with Armbian_19.11.6_Orangepi3_buster_current_5.4.7.img.
Thanks
