Yes, you’d use the USB VCP port class to do this. On the PC then the camera is just a serial port you open and read text from. Data will move at 12 Mb/s.
Note however, using this feature is not possible while debugging with OpenMV IDE.
So, alternatively, you can use one of he hardware serial ports on the OpenMV Cam and a serial to USB adapter to develop your app and then switch to the USB VCP port once you have all the bugs out.
