According to the PD 3.1 requirements (also PD 3.0), I need to connect UCPD1_CC1 and UCPD1_CC2 to USB-C CC1 and CC2 to communicate and request the desired voltage. But STM32G0B1KBU6  has only UCPD1_CC1 available. Is there any way to connect STM32G0B1KBU6  to USB-C to comply PD 3.1 requirements?

No, you need the CC2 pin to be exposed. Consider using a larger chip or the "N" version of the LQFP32.
