STM32CubeMX says non-existing SMPS must be enabled on STM32U5G7VJT6 (no Q)

Hello, I have a question about STM32CubeMX regarding the STM32U5G7VJT6 MCU.

STM32CubeMX 6/17.0 indicates that a non-existent SMPS power supply must be enabled for the STM32U5G7VJT6.
However, this is the version without the 'Q' specified in the part number:
Q = Dedicated pinout supporting SMPS step-down converter.

When I call SystemPower_Config(), the microcontroller does not work; without calling this function, it works fine.
Is this a bug in the STM32CubeMX, assuming only Q versions of this MCU exist?
