Have a read of this thread, first.
The TL;DR is that USB cables can affect audio, but not in the ways (or via the mechanisms) people like to imagine.
If you’re not getting dropouts, then any “performance” deltas are generally in the realm of the cable picking up EMI/RFI … and then the DAC also being sensitive to having that on the power lines of the cable.
Which is fundamentally about a) cable shielding and b) what’s near the USB cable in question and c) the design of the input stage in the DAC.
