Yes. That's basically PWM through a Low Pass Filter.
Use PWM to set the "duty cycle", which is the percentage of voltage. Then ise a low-pass filter (an inductor + capacitor, or resistor + capacitor) tuned to filter out the carrier frequency (should be around 500Hz if it's the same as an Arduino) to give you a voltage that is proportional to the ...
