Your post says "Nest Doorbell (wired Gen 2)", but I'm guessing you may have a 1st gen Google Nest Hello Doorbell. There are hundreds of posts in this forum about peeling or delaminating on the front of Nest Hello doorbells. It's happening on two of our three Nest Hello doorbells. Since Google Nest says they "cannot" replace such doorbells if they are beyond the 1-year warranty, we bought silicone skins on Amazon to cover up most of the peeling shards.
There is no way I know of to replace the delaminating plastic.
