Power Supply for STM32H757xI in package WLCSP156 - decoupling capacitors

[Ronil]

Hello all, for STM32H757xI in package WLCSP156, I didn't find a clear explanation about connecting capacitors for power supply. 

According to the schematic from STM32H757xI  kit, it looks like all VDD_MCU pins need to connect 100 nf capacitors, 

Only in my case, I can do that, since not enough place on the PCB

I wanted to ask, does it have any opportunity to connect VDD_MCU pins to each other and connect to more powerful capacitors. If yes, how can I calculate nominal for capacitors in this case 

I want to do like here

Did you see Application Note AN4938, Getting started with STM32H74xI/G and STM32H75xI/G MCU hardware development ?
