I don't think I have seen any alloy hookless rim brake wheels. Not sure if I have seen disc brake ones either. Stans wheels have a barely-there hook which is the closest I have seen to a hookless alloy wheel. Their Grail road/gravel rims have a bead and the very similar Crest rim barely has a bead.

Others here have much more experience than I do though.

Edit: Tom A said a lot of the same info while I was typing the original reply.
