Doubt regarding iMX95 PMIC output based on SoM design

i wanted to make a custom pcb based on iMX95 and i am using the iMX95 SoM schematic as the reference schematic.

As per what i understood, the PF09 will be the master pmic and will be making all the voltages except the soc and arm core voltages, these core voltages are made by pf530x.

My doubts are:
1. In the ref schematic LDO3 of PF09 is also making the VDD_SoC voltage line, why is it done?

2. And it is shown it can only source upto 200mA, but SoC current requirement is more than that, and if we both PF09 and PF530x is making the same voltages then it is like shorting the power lines, in such case will the pin at PF09 sink the current and then cause issues?

3. Should I/Can I remove the power output from Pf09 LDO and just use the other one, will it work? (give a clear suggestion, regarding "should i remove" or "can i remove")

images are attached below for reference
