Unfortunately this is not possible. 
You can flip the signal on both axes for a 180 degree rotation, 
but you cant rotate the image by 90 degrees, 
it is a hardware limitation, 
And here is nothing that can be done about it I'm afraid. 
You can mount the module upside-down, but not on it's side.

See this too.

At a technical level, 
the camera module produces the video images directly
 (as a jpeg stream) and the esp32 module simply passes this 
 already-encoded stream to the client. 
 Any attempt to rotate the image would need to be done in software, 
 and the esp32 lacks both the cpu speed, 
 and memory, to do this in real time.
