If you have a condensed keyboard, you’ll likely find a lot of value in installing a snippet manager, if you haven’t already. There is a lot of discussion on this forum about Espanso, which is a cross-platform snippet manager. You could define a snippet that would trigger that key for you.
Or depending on what your keyboard or OS is, sometimes these condensed keyboards have programmable overlays, where you can trigger alternative characters. If this keyboard is meant for programming at all, a backtick is a pretty essential key. If you share your keyboard model, maybe a keyboard enthusiast will have a more specific tip for you?
