iMX280 :  eliminate a  capacitance to GND

Dear community,

 

I design a custom board with i.MX280 .
As I hope to make the board as small as possible,
I would like to eliminate an unnecessary  capacitance to GND.

 

In the case of no battery and external loaded device connect with VDD4P2 pin,
Can I eliminate the 33uF capacitance to GND ?
Then the VDD4P2 pin connect to BATTERY and DCDC_BATT via a 1k resistor.

 

The VDD1P5 pin is same situation.
Can I eliminate the 33uF capacitance with VDD1P5 pin to GND ?

 

Best Regards,
Koichi Sakagami
