After going through really frustrated conversation with Apple tech support yesterday, and with this article, I would recommend not to DIY any T2-related part. Apple is not exactly being friendly to disclose further guidance for user to replace these parts. In fact even expert like OWC couldn’t crack down enough to provide compatible parts on iMac Pro.
With all the friendliness swapping out parts, this is an area you don’t want to get your hands wet.
