My mistake is in usage of smartd.  Not in smartd itself.  Even though smartd should be treat as daemon, I have treated it as just an auto startup program.  So I got: 

a. On an Apple Silicon Mac, smartd stops 30 minutes after execution.
b. On a Mac equipped with an NVMe SSD, the SSD information cannot be read.

After fix of smartd startup method, I no longer get those issues...

As a side note, this fix solved my issue regarding smartd continued from in the year of 2022.  The subject of the issue in this mailing list are:
