For the BR93Hxx-WC microwire EEPROMs there is a specification for connecting the test pin (Pin 6) to ground or open, but will there be a problem connecting it to VCC?
If the test pin (Pin 6) is connected to VCC write commands will be executed normally. However, if connected to VCC, please consider the BR93Hxx-2C series where pin 6 is NC.
