PXE boot pi 4?

I've got a FreeBSD server providing tftp/nfs4. With that I can boot a Pi 400 into Raspberry PI OS (trixie) over the network.

I'd like to be able to boot the client into FreeBSD. Anyone tried it? I don't have much idea where to begin.
 
I've been reading (and re-reading) these and other documents. Thank you both. There's a lot out there that only talks about x86 h/w, and more that only talks about Linux. Grr.

The 15.1-RELEASE that I have on my Pi's doesn't include PXE s/w. There's a directory in /usr/src/stand/i386/ (not encouraging); make build on a Pi didn't build it.

I have just found an encouraging write-up, <https://gopakumar.github.io/freebsd/linux/networking/freeebsd_diskless/> which

documents a working diskless FreeBSD setup on a Raspberry Pi (8GB) using a UniFi NAS (Debian-based) as the NFS server.

It assumes more knowledge that I have; I've never used UniFi. But I think this will point me in the right direction. I will now close about 40 tabs re PXE, linuxboot/kboot, initramfs etc.
