Software Solution

There is an App called Dual SIM Control that can manage the data and is compatible with Tasker however it costs 1.20 Euros. You can try the functionality in a free version (App no longer available). It claims to work without root but I don't know how it works.

Solution with Root

I researched a bit and found the following to turn off the data of one sim card in a dual sim phone with a SDK Version higher then 22:

public static void setMobileNetworkfromLollipop(Context context) throws Exception {
    String transactionCode = getTransactionCode(context);
    String command = null;
    SubscriptionManager mSubscriptionManager = (SubscriptionManager) context.getSystemService(Context.TELEPHONY_SUBSCRIPTION_SERVICE);
    // Loop through the subscription list i.e. SIM list.
    for (int i = 0; i < mSubscriptionManager.getActiveSubscriptionInfoCountMax(); i++) {
        if (transactionCode != null && transactionCode.length() > 0) {
            // Get the active subscription ID for a given SIM card.
            int subscriptionId = mSubscriptionManager.getActiveSubscriptionInfoList().get(i).getSubscriptionId();
            // Execute the command via `su` to turn off
            // mobile network for a subscription service.
            command = "service call phone " + transactionCode + " i32 " + subscriptionId + " i32 " + Settings.Global.getInt(context.getContentResolver(), "mobile_data", 0);
            executeCommandViaSu(context, "-c", command);
        }
    }
}

and

private static void executeCommandViaSu(Context context, String option, String command) {
    boolean success = false;
    String su = "su";
    for (int i=0; i < 3; i++) {
        // Default "su" command executed successfully, then quit.
        if (success) {
            break;
        }
        // Else, execute other "su" commands.
        if (i == 1) {
            su = "/system/xbin/su";
        } else if (i == 2) {
            su = "/system/bin/su";
        }
        try {
            // Execute command as "su".
            Runtime.getRuntime().exec(new String[]{su, option, command});
        } catch (IOException e) {
            success = false;
            // Oops! Cannot execute `su` for some reason.
            // Log error here.
        } finally {
            success = true;
        }
    }
}
