Hi Andrew,

I recommend looking at this FAQ for information on programming the OTP: [FAQ] BQ76952: Common questions for OTP programming with the Bq769x2 Device Family - Power management forum - Power management - TI E2E support forums.

For a stacked device, I recommend temporarily disconnecting their communication lines from each other and programming them individually so that if they share the same communication address you do not accidentally program both devices at once.
