I have a similar display.

Obviously rotating in 90 degrees does not produce a working display at all. (display_rotate=1)

Rotating 180 degrees does nothing. (display_rotate=2)

So my guess is that you can not rotate this display at all.

Oops.. I spoke too soon.

In the manual it says:

I have to try this...

Works like a dream... I tried rotate=180 and rotate=90.

So you need to edit /boot/config.txt

The dtoverlay sentence at the bottom of the config file.
