Simultaneous/synchronized start of ADC conversions without DMA

The microcontroller i am using is a STM32F446.
The STM32F446 is equipped with 3 ADCs.
I would like to start one conversion of all 3 ADCs at the same time (simultaneous/synchronized start).
I do not want to use DMA.
I would like to start the conversions by software (no external trigger) and to poll if the conversions of all 3 ADCs have finished.
Is this possible and how do i have to configure the ADCs for doing this?
I searched all given examples by CubeHAL and StdPeriph_Lib but didn't find anything that fits.
Searching the internet for "Triple regular simultaneous mode, -DMA" and things like that was also quite disappointing.
Any help is greatly appreciated
