powering sequence of ADN2850

Hello

I am going to replace a resistor with a digital resistor ADN2850. The resistor is connected in series with a reverse biased photodiode (PD). In a data sheet for the ADN2850 I have read that a powering sequence is required (Rev. E | page. 15). Namely VDD must be powered before applying any voltage to Terminal B or Terminal W. In my design, power supply is applied to a cathode of the PD. One end of the resistor is connected to anode of the PD, the second end is grounded. Do I have to delay powering on the PD taking assumption that on powering a photocurrent is close to zero - the PD is not exposed to light?

Best regards
