Install Fan for Argon one M.2 (Cannot find I2C)

Configuration
1

I’m unable to get the Fan of the Argon one M.2 working

System: PI4 8GB with SSD in Argon one M.2 - Home assistant 2021.10.6
ArgonOne Active Cooling Current version: 24.1 Installed via Supervisor (seems ok)

Next i tried to enable I2C VIA HOME ASSISTANT OPERATING SYSTEM TERMINAL
https://www.home-assistant.io/common-tasks/os#enable-i2c
No messages when using SDA1 (in contrary to sdb1 or Mmcblk0p1)
In the home assistant log-file i get this log:

Hi, maybe solved in '21 but now we have '23 …

I am using HA OS Version: 9.5, Homeassistan Core: 2023.3.6 and argone addon Version. 29c.
To enable I2C I also used HassOS I2C Configurator Version: 013a.
I use ssd usb drive as system drive.
What ever I did it was/is not possible to run that argone fan control.
It was / is not possible for to create /dev/i2c etc. at all.
I read several articles on the net and watched videos - but without success.
It seems that the newer Version of Home Assistant doesn’t to support I2C on Argon One M2.
By the way i2c support enabling in config.sys didn’t work either.
What a pitty - I think I must switch to another case with normal fan control over gpio pins
