How to choose config file as command-line argument and present result in the console while maintaining modularization?

Question

config.ts:

export const data = 'Config';

process.ts:

import { data } from "./config.ts";
const calculated = data + ' is used.'
export {calculated}

main.ts:

import { calculated } from "./process.ts";
console.log(calculated)

> deno run main.ts
Config is used.

Now, I want to be able to choose configuration via command-line argument. That is:

> deno run main.ts config1
Config1 is used.
> deno run main.ts config2
Config2 is used.
> deno run main.ts config3
Config3 is used.

Is this possible?

To solve the static import and Uncaught ReferenceError: Cannot access 'configToUse' before initialization, I use dynamic imports and wrap everything inside functions. The code becomes:

process.ts:

async function calculate(configToUse) {
    const pathToConfig = './' + configToUse + '.ts'
    const config = await import(pathToConfig)
    return config.data + ' is used.'
    }
export {calculate}

main.ts:

import { calculate } from "./process.ts";
const configToUse = Deno.args[0]

calculate(configToUse).then((result) => {
    console.log(result)
})
