Possible to substitute *and* disable my 'n' key?

Is it possible to disable a stuck key on the keyboard? My 'n' key is stuck so I am wanting to map that to semicolon key since i rarely use that, but I would also have to disable my n key since it keeps triggering without me touching it!

Many thanks anyone who knows!

Sorry, BTT can not do that. Maybe the app Karabiner Elements can help, but I'm not sure.
