Per https://lists.freedesktop.org/archives/amd-gfx/2018-May/022021.html it seems that AMD developers lack hardware to implement LVDS/VGA support at this time. KABINI devices with VGA, DVI-I and/or LVDS connectors are still possible to buy in the market. Supermicro H9SKV-420 Fujitsu D3313 both available via ebay. In Europe one can find pre-owned Medion E1317T and E1318T too.
