Some hidden things the Note 8 still has from its predecessors (but also dependent on whether the carrier blocked it or not)...
1) Developer Options: Settings>About Phone>Software Information - tap the "Build number" multiple times (it will even show a count down of taps) to enable it
2) Diagnostic Tools: Access the phone and press *#0*#
On my Verizon phone you simply do Settings>About Phone>Build Number>tap tap tap until you become a developer.
