Could you please double-check this? Riva and Rolex seem to have
properly different values there, but this one mimics one of the
values for Rolex.

FWIW these values are almost never properly fused so I wouldn't be
surprised if this was a fail.

riva value is depends from the bootloader, Oreo bootloader using same 
value
like rolex and tiare, 2nd entry in the board-id is not used so i should 
remove it.
Here is some more context:

These properties exist for the sole reason of making the bootloader
happy, so if there's nuance, let's not try being too smart and just
stick with what works
