It does support arm!! Most arm devices do not support UEFI though, and have very proprietary boot processes requiring custom kernels and such, so your milage may vary. UEFI arm (like on Libre Computer boards) will work flawlessly.
For rpi images i think the best option would be PINN; but it’s not a 1:1 equivalent since every time you add an image it needs to wipe partitions and start from zero.
Does it work for Raspberry Pi images?
Unlikely, as it doesn’t support ARM to my knowledge

You typically image directly onto the SD card for a Raspberry Pi, not off a bootable drive.
