Yes, I have read from VU2ESE that the there is no more room on the Arduino. I found a pretty reasonable priced Nextion 2.8¡± (for USA, anyway) at RobotShop.com .

As one can see from the picture, the SD card socket is not connected to anything.
It's there because the original design it's cloned from had one and it has stayed.
It does allow having images and other stuff on an SD card if using some small microcontroller like most arduinos.
But I, doubt there's any space left in the arduino used in uBITX for the filesystem and other stuff to make any use of it.
