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?

I have a nano-vna with a hardware version of 4.3_MS and it has firmware version 1.2.27
It has SD card function and clock
I hope this can give you some references
