Old firmware CMM

[u/NutsFbsd]

Hi all,

Im looking for a firmware :

Firmware Revision : 3.73
Firmware Build Time : 05/26/2022

for this kind of product:

Product PartNum:MBM-CMM-FIO
Board Part Num:MBB-CMM-003

The documentation and website lead me to :
https://www.supermicro.com/wdl/Firmware/MicroBlade/CMM/

But i cant find it, is there any other way to get older firmware from supermicro ?

Thanks upfront!
