STM32H723 SWDv2 multidrop

[hhammoud94]

I'm looking to program multiple STM32H723 chips on the same board through the same programming interface. I'm currently using SWD. I see in the documentation that multidrop is supported but I don't see any information about how to program the instance ID to be different across the different chips on the board. 

Is this possible? Or did ST also hardcode the instance ID to all 0s? 

If not possible with the H7 series, do you have any series that support changing the instance ID? 

Thank you

The chip supports it, but no ST-Link programmers do.

It is hardcoded on the H5. Probably the same on the older H7.
