Absolutely! You can use the DAQmx Base C API in LabWindows/CVI. You will need to make sure you have NI-DAQmx Base installed. You can get the most recent version
here. Attached is a CVI project that uses the DAQmx Base shipping example "acquire1Scan.c". You will need to make sure to either include "NIDAQmxBase.h" and "nidaqmxbase.lib" in your project or include the correct search paths for those files. They are in the DAQmxBase directory in "Include" and "Lib" folders respectively. Hope this helps!
