Apologies for any misleading instructions you may have received. The table on the bottom of this page should be up-to-date for which overlays to use for which Toradex peripheral: Device Tree Overlays on Torizon
Please note the accessory column, as there’s multiple accessories that give LVDS functionality here. The list of overlays you have seems to mix the mezzanine accessory and the DSI to LVDS adapter accessory. But I guess it still works fine enough it seems despite the mix.
