No, I'd shut down completely before removing the stick--if that's what I wanted to do.
But I'd reboot a few times and walk through the process a few times to gain familiarity. Type up some instructions that you can refer to later.
If you DON'T hit F12 or use the Novo Button, the PC should just ignore the USB stick and boot normally, as if the stick was not connected.
You are going to be revisiting Macrium pretty soon anyway assuming you actually make an image file and are going to at least simulate a restoration.
Figure stuff out when the heat is off, not after you've had a disaster.
