We don't understand the bit SCUEN of STM32H7.
The description is not very clear:
Could you explain what SCUEN means and if the software is supposed to write or read this bit and why ?

Where have you seen this? I tried to find in my STM32H7 manuals but I do not see anything for SCUEN.
Where is coming from? (provide doc name, link and page as info, thank you).

It's in the technical reference manual, nothing exotic...

No SCUEN bit in RM0468 for STM32H723/733, STM32H725/735 and STM32H730

We are looking at RM0433 review 8
§6.4.1
The 21st figure describes the hardware start-up procedure but its unclear wether software or hardware is responsible of its use

Okay, RM0433.
You should always say which STM32 / H7 exactly you are using, even in the "basic" registers there seem to be some differences between the H7 types.
I would check how the HAL libraries are using this bit, if they are using it all.
