Vue 3, dynamic MapChart JSON

[fermevc]

Is it possible to dynamically import second argument in registerMap() function?

import json_data from "@/assets/json/map1.json";

...

registerMap("map", json_data);

I've tried many things (ref, computed, props, iife, ...) but when I manage to solve all errors, I cant see the map. I've tried to set a key on VChart component to re-render it when prop is changed, but nothing happens...
If I do a standard "import JSON_DATA from "@/assets/json/map1.json;" everything is working OK.
The idea is to dynamically change MapChart "geojson source" using select input whose option values represent file names (map1, map2, map3, ...).
Thanks in advance!
