Don’t buy intel? I believe they require the fuses blown. A company can’t just “say” these are “developer” laptops, or else FW would already be doing it. Framework did have a few actual developer laptops, without fuses blown. But they were given directly to active developers, not just for sale.
You should confirm by asking FW support directly, but I believe AMD boards don’t have PSB.
There is a coreboot thread here, community.frame.work/t/responded-coreboot-on-the-framework-laptop/791
