If you are OK with it, LabVIEW is trivial to pirate, just search around and you may find a small exe that activates LabVIEW editions from ancient to 2023. Or you can either try to hack with the daqmx python binding or using the C++ API, although your mileage may vary, depends on your skill.
There is one thing for sure, you will have to do some programming, it may be just dragging a few boxes together in LabVIEW or writing tens of lines of straightforward code in Python. It may be a challenge for people used to work with ready made front pannels, but this also gives one the maximum flexibility if one enjoys that. I used my USB-6259 as a dynamic signal analyser, low frequency frequency response/impedance analyser, peak counter/MCA when playing with radioactivity detectors,calibrator for some old meters and a voltage source for driving the gate when doing IV mapping with a Keithley 238, all with low effort python scripting.
