Falcon mode assumes one dtb, so you either patch your based device tree or you manually use fdtoverlay to apply the overlay to the base dtb:

voodoo@hestia:~$ fdtoverlay --help
Usage: apply a number of overlays to a base blob
	fdtoverlay <options> [<overlay.dtbo> [<overlay.dtbo>]]

<type>	s=string, i=int, u=unsigned, x=hex
	Optional modifier prefix:
		hh or b=byte, h=2 byte, l=4 byte (default)

Options: -[i:o:vhV]
  -i, --input <arg>  Input base DT blob
  -o, --output <arg> Output DT blob
  -v, --verbose      Verbose messages
  -h, --help         Print this help and exit
  -V, --version      Print version and exit
