I was having the same problem. I found a workaround by using a different constructor from the base DbContext class:

public DbContext(DbConnection existingConnection, bool contextOwnsConnection);

Using this override you can pass an SQLiteConnection instead which you set the connection string on. So for example you can add a new constructor to your FirmwareContext.

public FirmwareContext(string connectionString)
    : base(new SQLiteConnection() { ConnectionString = connectionString }, true)
{
}

Or even

public FirmwareContext(string filename)
    : base(new SQLiteConnection() { ConnectionString =
            new SQLiteConnectionStringBuilder()
                { DataSource = filename, ForeignKeys = true }
            .ConnectionString }, true)
{
}
