Use NI USB 6001 without the Data Acquisition Toolbox

I have a measurement system running on Matlab 2014a on an old laboratory computer. I purchased an NI USB 6001 to produce an analog output using that lab computer. The issue is that due to security reasons, the company prohibits to connect that lab PC to the internet, which makes it difficult to install the data acquisition toolbox needed to interface matlab with the NI USB 6001.
Is it possible to communicate with the NI USB 6001 card with matlab, but without the data acquisition toolbox?

It is, using the .net DAQmx driver...some code lines ...
NET.addAssembly('NationalInstruments.Common');
NET.addAssembly('NationalInstruments.DAQmx');
import NationalInstruments.DAQmx.*;
obj.DaqSystem = NationalInstruments.DAQmx.DaqSystem(); % init DAQ System
...
function device = loadDevice(obj,deviceName)
% try to load requested device by alias
devIndex = obj.Devices.DeviceID == deviceName;
if any(devIndex)
obj.CurrentDevice = obj.DaqSystem.Local.LoadDevice(obj.Devices.DeviceID(devIndex));
else
assert(false,"Error@DAQmxBase load device failed " + newline + "devices found are " + obj.Devices.DeviceID.join)
end
device = obj.CurrentDevice;
end
