What are you using as a source? If using a PC/NAS or external hard drive...
On the cheap you could use a network-connected Raspberry Pi to control the source and output USB from the pi to the DAC. Then use Volumio/Moode/Rune as the control software (via PC of smartphone) and enable software volume control. Or a deluxe method would use a MicroRendu and your choice of control software like Roon or Lumin or many others.
