What is this 4 pin header on the Creality 4.2.3 board?

Question

What might these 4 pins be on the Creality 4.2.3 board be?

The silkscreen says

G
SC
SD
V

It is next to the pin header for the LCD, so I suspect it is either a UART or TFT port.

Googling I suspect SD might be short for SDA and SC might be short for SCL. Which are common I2C pin descriptions.

I found the unofficial schematics for the very similar 4.2.2 Creality board.

It contains a 4 pin header titled ICSP port. Note that these appear to be 3.3 V pins
