Any hope for multiphase using the f072 mppt

I’ve been struggling with pwm phase shifting for the STM32f0 version of the mppt, but no good source of information or reference online.
Any hope of introducing multiphase buck type using the STM32f0 .
Am not too familiar with STM32 that’s why I found it difficult .

Unfortunately, I don’t think I will develop any more charge controller based on the STM32F072. I will completely switch to the STM32G series for new designs. And I’m currently not planning to develop a two-phase design.
