UEFI boot works on FreeBSD, it's only the UEFI Secure Boot that doesn't 
work yet. It requires the bootloader to be signed with a key known to 
UEFI. You would need to disable Secure Boot and just leave UEFI boot in 
order to boot FreeBSD.

The other thing that apparently doesn't work with UEFI is switching from 
UEFI boot console/fb into amdgpu console/fb. The first needs to be 
disabled with a sysctl switch. However, this doesn't affect my desktop 
so it seems it's not an universal "doesn't work".
