Does STM32H747BI have a internal DSI regulator? There is no VDDDSI pin of LQFP208 package. Need an external 1.2V power supply?

I am facing the same problem. According the Datasheet the STM32H747BI has two VDD12DSI pins but no VDDDSI pin. On the other side I could not find any information that the internal DSI regulator is not existing in all derivates.

Does anybody know, if the STM32H747Bi has the internal DSI regulator or not and, if yes, where the supply pin for it is?

Best Regards
