Great. Thanks for the reminder about the T2 chip. For completeness for future readers I found this white paper by Apple:

I do have one additional question based on a snippet from this white paper:

“External Boot policy

“External Boot policy controls whether a Mac can be booted from external 
 media. This policy is shown only on Mac computers with the T2 chip and is independent from the secure boot policy. Disabling secure boot doesn’t change the default behavior of disallowing boot from external drives.”

Do you advise (or is Apple implying) that booting from an external drive makes one’s backups less secure?

Thanks again!
