Sorry Mark, but what you say is wrong ,

Open the RaspberryPi-imager tool ( I’m a Mac-user, so got the Mac-version) ,
Goto -> 
ChooseOS-> Ubuntu-> Ubuntu 20.04.1 LTS (RPI3/4)/64-bit server OS for arm64 architectures…
Let it write to SD or USB… then mount the ubuntu-msdos-partition and copy over the whole crap 
to your FreeBSD-USB-boot-media for the 4GB-model ….
 enjoy to see FreeBSD booting from USB without SD_card …
Perhaps you will stop enjoying the greatful boot-process when it will hang short before it initializes RobOCrow`s pcie-driver  :-) Ha Ha
but it boots 2020.10 and that’s the first step before fixing the hang...
