The Gekko version of the early nanoVNAs had the solder pads for an SD card
slot - look at my forum photo from almost a year ago.
I actually added a slot to mine but then sold the unit and bought a better
made one (no SD pads).

I have ordered an ST32F303 and I'm looking for the proper LCD panel so that I
can convert my H into an H4.
I will add an SD slot to the PCB as well.

No for H need compile its own firmware, it have about 14kB free flash. Only
Fat32 and short filenames need ~10kB (but i don`t test this for H firmware)
Also H version not have SD slot on PCB board, need add it, but this difficult
for me (for my test).
If SD card on this board connected as on H4 board, possible compile firmware version for H vs SD Card support

You should understand
1 - Most Display module for H4 (ST7796S driver) like this
Have 40pin connector
H version use ILI9341 module like this
Have 18 pin connector
Yes possible replace it, but ... i don`t know, you have to overcome many difficulties
