I know of exactly 1 AMD corebooot laptop. Starlabs Starfighter.
For coreboot you’re basically on Intel. As others mentioned, look up dasharo. They have added support for two modern MSI motherboards and Intel cpu models.
In case you haven’t seen it already - 3mdeb shared some info on the state of things during last FOSDEM. If I’m not mistaken they also did an update the year before too.
