I suspect there's no issue to fix but rather you have to manually set those keybindings in your hyprland conf.

Re: brightness button fails to properly map on hyprland

Hyprland is not a DE, it is a WM. DE's are mostly feature complete and set up already for you. WM's on the other hand, you have to configure the features you want. Using function keys to control brightness is one of those things you have to set up on your own in Hyprland. The Hyprland wiki has all the info you need about binding. Try binding first and then see if it's a driver issue or a missing config.

it is already binded as

bindel = ,XF86MonBrightnessUp, exec, brightnessctl s 10%+
bindel = ,XF86MonBrightnessDown, exec, brightnessctl s 10%-

its just that acer_wmi is not binding the function keys to

XF86MonBrightnessUp & XF86MonBrightnessDown
