Query regarding Power Up of STUSB4500

I was working on a project of power delivery using STUSB4500. I am configuring the STUSB4500 registers using a Nucleo F07. So, my query is whether we can connect the Nucleo Board for UART / I2C Connection and the Type C Power Adapter for Source Input to STUSB4500 simultaneously? Will the 5V output of STUSB4500 and the U5V pin of Nucleo Board interfere and damage the board? I am worried whether two 5Vs will damage the board or not. I have not found it mentioned this configuration anywhere. So, if I want to simultaneously connect the PD source and also receive UART data through Nucleo Board, what should I do?
