Unfortunately I don't think that has been implemented. If you want to have a go at it you can find the implementation in the Crazyflie here ... Tdoa2Tag.c

It is probably fairly straight forward to convert it since it uses the same DW1000 library. The output from this code is the raw TDoA values though and to get a useful position out of it you will have to some sort of estimator after that. Most likely the Node will not have enough CPU-umphf to do that, so you probably have to stream the TDoA values out from the Node into another device for further processing.
