I'm not sure if this will solve your problem, but you can find JDBC drivers in the installation folder:

Installation folder > dev > java > lib > 1.8

You'll find the file intersystems-jdbc-3.6.1.jar. I believe you can use this to connect to Power BI, if necessary.

I would try to install the Caché client on these laptops, some machines at my old company had a similar problem and that solved the problem.  

Normally I create a volume in the docker-compose.yml file to share data between the container and my machine. I define the durable directory in this volume, so when I restart the container I don't lose the data stored.

version: '3.6'
services:
  iris:
    build: 
      context: ./iris
      dockerfile: Dockerfile
    restart: always
    container_name: iris
    ports:
      - 51773
      - 52773:52773
      - 1972:1972
      - 53773
    volumes:
      - ./iris/data:/durable 
    environment: 
      - ISC_DATA_DIRECTORY=/durable
    networks: 
      - production-network

When I had problems with Cors I use overload of methods in my SuperClass to solve this problem.

ClassMethod HandleDefaultCorsRequest(pUrl As %String) As %Status [ Private ]
{
    Do %response.SetHeader("Access-Control-Allow-Origin","*")
    Do %response.SetHeader("Access-Control-Allow-Credentials","true")
    Do %response.SetHeader("Access-Control-Allow-Methods","GET, PUT, POST, DELETE, PATCH, OPTIONS")
    Do %response.SetHeader("Access-Control-Allow-Headers","Access-Control-*, Content-Type, Authorization, Accept, Accept-Language, X-Requested-With, Origin")
    
    Quit $$$OK
}

I think the same, Flutter is easier to develop in my opinion, but it's just personal taste.

Try to acess in your local machine this folder. There are some examples to acess the database.
