Changing the "drop all"/"drop stack" keybind in Minecraft

I’m experimenting to find the most comfortable keybinds for me and I found that Ctrl would be perfect for dropping items. However Ctrl + [drop item key] drops the whole stack, which is also the case for Ctrl+Ctrl, meaning that I can’t drop single items with this setup. Can I change the "drop all" keybind to something else? Anything goes, I’ll even gladly install a mod if it allows that.
