I'm noticing that on the developer board CY4532 in Powerbank configuration the P_CTRL_FET line is disconnected from the drawing you sent me recoverable some time ago at this link
Why is he disconnected? What should I take into consideration?

Hi ,
CY4532 do not use two separately path for provider and consumer path. It is only use VBUS_C_CTRL for power bank of Type-C port's provider and consumer path. You could see the VBUS_C is short to VBUS_P on power board.

Hi,
The Blog is sharing the firmware example for single C port. I am not understand your question about P_CTRL_FET line is disconnected from the drawing you sent me? It seems your question is based on Hardware schematic? Could you please kindly specify it?

Below the image shows what I meant ... in the blog example P_CTRL is interconnected while in the schematic of the developer board CY4532 it is disconnected by default. Can you give me a clarification on this?

Thank you very much!
So is it advisable to use both consumer and provider fet or use only one?

Hi ,
it is advisable to use both consumer and provider fet.
It is okay and verified to use only one path if the DC/DC have capabilities to configure the direction - Charging or Discharge. If you select this way, VBUS_C_CTRL is the recommended control pin.
