If you don't have coding skill, you can use some REST API console like postman. Note that the Set All Connections only works for the datasets in DirectQuery mode. For import mode, there's no way to update the connection string, AFAIK.

Steps to perform the post method in postman. Where to get a bearer token?

A sample connection string for SQL Server database.

    {
    "connectionString": "data source=wx-sql-test-01;initial catalog=UserVoiceDB;persist security info=False"
        }

At last, add a datasource in the gateway for the datasource in the new connection string.
