I am observing a surge startup current of 0.1 to 0.2 mA when I am powering the nRF24LE1 module. Is it possible that the device can startup in power saving mode? Is there a way we can prevent the surge startup current?

While the chip is in reset state (for instance VDD ramp up and settle) and until code execution put the chip in sleep state, then it will likely draw current in the range you state.

Could you provide some sample code for this such that at startup the chip is in register retention mode or something
There will also be some "inrush" as capacitors on your board charge, etc ...
Waiting for your reply.
You should have already received links to multiple examples that put the chip to power down mode here:
