Rebind / key so it doesn't open chat

So this is probably a unique issue, but I play left handed and rebound my keys to work on the right side of the keyboard. One of the issues is that if I accidentally press / it opens the chat menu expecting a command. Does anyone know a way to unbind this, or to stop it from doing that? I know there are ways to do it on the keyboard side or with other software, but I’d rather not disable the key completely since I use it also to type and would lose out on the ?
