With specific wiring, you can control pixels outside the pixel driver's voltage range. As long as the pixel driver has the ability to control the pixels protocol.
For the wiring, your pixel driver will need to pass data and ground to the pixels. While you use a separate power supply (with the voltage of the pixels) to splice in VCC & ground to the pixels you are using.
This arrangement ensures that voltage is not passed directly from your pixel driver to the pixel strip - which ensures that neither the driver, not the pixel strip is damaged by over-voltage.
