Finally, I renounced to install JetPack 6 from SDKMANAGER.
I directly flashed the jetson bios to update QSPI bootloader from the terminal with commands and separatly I flashed the sd card from my windows system.
It works fine.
Here, the useful post to realize it :

I used standalone ubuntu not Wsl, so I followed only the steps for ubuntu.
Useful documentation :
https://docs.nvidia.com/jetson/archives/r36.2/DeveloperGuide/IN/QuickStart.html
It’s so faster and easier than to use Sdk manager… I lost 2 days trying with sdk manager…
