Purism Librem 14

I am trying install FreeBSD-13.1 on a Purism Librem 14. Alas, FreeBSD
cannot make it to a boot menu.

I have other Purism devices (Minis) on which FreeBSD works fine,
and OpenBSD runs fine on the Librem 14.

Some preliminary Googling suggests this is an interaction between
FreeBSD and Coreboot or SeaBIOS. Indeed, the Minis are using SeaBIOS
1.14 while the Librem uses 1.16.

Anyone else been down this road and have some insight to share?
