I can confirm that currently the only way to exit USB mode is to toggle the power switch. I'll look into adding a register to allow changing modes.
The USB interface always outputs raw, uncalibrated values, as is in the user manual. The reason is the assumption that the PC software always has superior calibration routines (e.g. supporting arbitrary cal kit parameters) and it is far less error prone if you can't be confused whether you are readin calibrated or uncalibrate values.

Gabriel,
Thanks for your response. I understand blanking the display while NanoVNA-QT or similar programs are running to increase the speed of data transfers. Plenty of commercial applications do the same thing. For small scripts, where you just want to work with the trace data currently on the display, it would really help if you could add a firmware command to un-blank the display, and also a firmware command to transfer corrected CH0 and CH1 data.
Do you know it the client, HCXQS group, plans on a support forum for the S-A-A-2?
Regards,
