ATTiny817 | TCD For PWM

We are needing to generate a PWM signal on pins PC0 and PC1 which are attached to TCD timer on our ATTiny817. However, we cannot seem to successfully output a PWM waveform in order to dim LEDs on these pins. Traditionally we use analogWrite to dim these LEDs and we are successful with those pins attached to TCA and TCB however TCD does not appear to be supported by default with analogWrite.
