There's physically no way to permanently "brick" an iPhone.
DFU mode boots entirely from read-only ROM, and from there, you can just restore everything via USB cable.
Same applies to Apple Silicon Macs. You can damage the system, recovery and emergency recovery volumes, but even then, you can still boot into DFU from ROM and re-initialize everything via another Mac.
This is in contrast to some PCs, where if you damage the BIOS (e.g. by suddenly losing power during a firmware update), your device may or may not be bricked. There have even been stories of peoples' computers being bricked via rm -rf /, due to removing everything at /sys/firmware/efi/efivars/ (which is actually stored inside the motherboard), and sometimes contains things that the motherboard won't boot without
