iMac Pro - Spontaneous Reboot (Bridge OS)

How do I resolve the "Bridge OS 2.x" issue (e.g. spontaneously, without warning, powering down)?

It is distinct, it is quantifiable, and it appears to be tied to the new Apple T2 processor.

I've seen a number of these posts -- many that have been closed -- but I'm unable to identify a solution, and Apple Support has not shared a resolution to this known issue.
