Or just set up a browser search keyword/engine to go straight to Google Maps if that is what you want. I have Kagi as my default but have a small handful of keyword bookmarks set up for when I am making something that isn't a general web search. "m <location>" for Google Maps, "i <title>" for IMDB, "p <query>" for Kagi image search, "d <query>" for D&D Rules Search, you get the idea.

This way Kagi doesn't even see my query, I don't need to wait for the redirect, I get to set up the shortcuts myself and I can switch any of my search providers (even the default) without affecting my "bangs".
