For STM32L552 with external SMPS (variant P). This variant has dedicated pins for VDD12 external power supply, but suppose I did not wish to use this SMPS, instead using the standard linear regulators. How do I connect the two VDD12 pins as unused?

The datasheet indicates they're not connected when LDO is used, in which case you can leave them floating.
