Gigabyte support confirmed it. This is correct. The answer to my CSM (legacy boot) related request translated from German to English (US) by https://www.deepl.com/de/translator : "Dear Gigabyte customer thank you for contacting us.

The OS Linux is not supported by us, also we do not offer drivers. Your GIGABYTE Team"
