I'm afraid I'm not sure I understand what you want to achieve.

Please note that FreeBSD HEAD supports booting Xen from UEFI now also,
so you are no longer tied to using legacy BIOS.

If you want to boot Xen you need to install the xen-kernel package and
add the xen_kernel and xen_cmdline options to your loader.conf, see:

https://docs.freebsd.org/en/books/handbook/virtualization/#virtualization-host-xen

You likely also want to install the xen-tools package in order to
manage VMs.
