For the G13 there is also a GUI tool.

Ubuntu 25.04 plucky currently has kernel 6.14, 24.04 noble only 6.11.

Debian 12 bookworm has 6.1 and the recently “frozen” 13 trixie has 6.12.

For Debian bookworm, the non-free AMD graphics drivers firmware-amd-graphics date from 20230210 (backported: 20241210) and for trixie 20250410.

I don’t know how up to date the amd firmware versions in the Ubuntu release are.
