Answer 1

In Magento 2 There is payment Method "Zero Subtotal checkout".

You just enable it. It will automatically appear when your total is zero and for hiding other payment we you have to do some customization.

Answer 2

You can use the below in your Model\Payment\paymentMethod.php file

    /**
     * @param \Magento\Quote\Api\Data\CartInterface|null $quote
     * @return bool
     */
    public function isAvailable(
        \Magento\Quote\Api\Data\CartInterface $quote = null
    ) {
        /*return parent::isAvailable($quote);*/
        return parent::isAvailable($quote) && !empty($quote) && $quote->getGrandTotal() <= 0;
    }
