I don’t use BiaB for this kind of work but I think this will work. Unfold your song into one long chorus then in the Piano Roll View highlight that section and raise it one octave. That should raise that section one octave while leaving the others in the original octave.

Good luck.

Why does toilet paper need a commercial? Who's not buying it?

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
