There are versions out there but afaik it’s super awkward to find them, I’ll see if I can find the one I used a couple months ago again and send a link here if I do

There’s a big one by Mike Schley. Most smaller ones are relatively old or just crops of that one.

…new sourcebooks coming next year, but fourth-edition maps kind of butchered the realms and third-edition maps compressed them into a fantasy theme park: i appreciate the proper scale of the fifth-edition map even if broader setting resources mostly entail tracking down older reference material…

…fifth edition does offer officially-sanctioned sourcebooks for the moonshaes, border kingdoms, thay, chult, and icewind dale in addition to the sword coast, though; you just have to delve into the DM’s guild for adept and adventurers’ league material…

…third-edition maps do alright in a pinch as long as you double the distances…

Try this one. As the comments of the post say, it’s not entirely up to date, but it works well enough.
