Of course it can be used. Have you tried it? I have a dozen Due's happily receiving data on Serial with no problems.
What is your suggestion? Should I desolder the tiny line buffer, cut the ground plane/trace, and make a solder blob between #OE and Input? Or is it easier to cut the output trace as I indicated in my screenshot and add a 1K resistor between the buffer output and the RX input pin of the chip? (Presumably both solutions will work the same)
The first replicates the latest Due schematic, so would be the "safe" choice. Those little chips are quite fragile though, I destroyed one in my first attempt at rework.
