Help needed for Realtek RTL9210B NVMe/USB 3.1 Controller firmware Version 1.33.5

Hello to all. I have a Realtek usbc nvme case adapter (with fan) that came with the firmware version 1.33.5 with date 2023.10.06 . I saw that this firmware is not shared by anyone in the forum so i wanted to ask if it is possible to dump the firmware in a non destructive way ( desoldering the chip ) . Below i include some photos .

There is no tools to dump Realtek firmware
I dumped a RTL9201R a while back by removing the chip
the only way to flash it back on is via a programmer
there doesnt seem to be a simple way to make a firmware thats flashable
with Realtek's flasher

tbh there's no real point dumping it we have plenty of firmware's for the RTL9210B
with 1.33.98 being the latest

just dump the device info (nvram) with the flasher
and clone them settings before flashing the latest firmware

Thank you for the info . It was probably your post i saw that made me question the viability of dumping this firmware without manual intervention. So i guess there is no need for such firmware .One question though , is there a guide pointing to flashing realtek firmware ? Jmicron and vli were the only ones i have tried in the past and in hdd cases that were missing the fan . My main fear is that fan will stop working.

PS Is this guide a valid one github
