sd card implementation

[dr-onestone]

I possess a nanoVNA-H4 with HW version 4.2.1 (printed on the PCB inside), bought at about the midst of 2021 from alibaba. There are already solder points on the board for the implementation of a sd card socket. I want to ask whether I have to implement/change some additional hardware components or wires to successfully integrate the sd card. In addition I want to know the firmware version I have to update for a successful integration of the sd card. My current running software version is 1.2.00 [p:401, IF:12k, ADC:384k, Lcd:480x320] Architecture: ARMv7E-M Core Variant: Cortex-M4F Platform: STM32F303xC Analog & DSP TCXO = 26.000 000 MHz

In addition my date and time is not working correctly. What do I need to change/implement?
