I want to remove the below lines in MagentoQuoteModelPaymentMethodManagement model file

 if (!$this->zeroTotalValidator->isApplicable($payment->getMethodInstance(), $quote)) {

            throw new InvalidTransitionException(__('The requested Payment Method is not available.'));

        }

In PaymentMethodManagement file:

<?php

/**

 * Copyright © Magento, Inc. All rights reserved.

 * See COPYING.txt for license details.

 */

namespace MagentoQuoteModel;



use MagentoFrameworkExceptionStateInvalidTransitionException;



/**

 * Class PaymentMethodManagement

 */

class PaymentMethodManagement implements MagentoQuoteApiPaymentMethodManagementInterface

{

    /**

     * @var MagentoQuoteApiCartRepositoryInterface

     */

    protected $quoteRepository;



    /**

     * @var MagentoPaymentModelChecksZeroTotal

     */

    protected $zeroTotalValidator;



    /**

     * @var MagentoPaymentModelMethodList

     */

    protected $methodList;



    /**

     * Constructor

     *

     * @param MagentoQuoteApiCartRepositoryInterface $quoteRepository

     * @param MagentoPaymentModelChecksZeroTotal $zeroTotalValidator

     * @param MagentoPaymentModelMethodList $methodList

     */

    public function __construct(

        MagentoQuoteApiCartRepositoryInterface $quoteRepository,

        MagentoPaymentModelChecksZeroTotal $zeroTotalValidator,

        MagentoPaymentModelMethodList $methodList

    ) {

        $this->quoteRepository = $quoteRepository;

        $this->zeroTotalValidator = $zeroTotalValidator;

        $this->methodList = $methodList;

    }



    /**

     * {@inheritdoc}

     */

    public function set($cartId, MagentoQuoteApiDataPaymentInterface $method)

    {

        /** @var MagentoQuoteModelQuote $quote */

        $quote = $this->quoteRepository->get($cartId);



        $method->setChecks([

            MagentoPaymentModelMethodAbstractMethod::CHECK_USE_CHECKOUT,

            MagentoPaymentModelMethodAbstractMethod::CHECK_USE_FOR_COUNTRY,

            MagentoPaymentModelMethodAbstractMethod::CHECK_USE_FOR_CURRENCY,

            MagentoPaymentModelMethodAbstractMethod::CHECK_ORDER_TOTAL_MIN_MAX,

        ]);

        $payment = $quote->getPayment();



        $data = $method->getData();

        $payment->importData($data);



        if ($quote->isVirtual()) {

            $quote->getBillingAddress()->setPaymentMethod($payment->getMethod());

        } else {

            // check if shipping address is set

            if ($quote->getShippingAddress()->getCountryId() === null) {

                throw new InvalidTransitionException(__('Shipping address is not set'));

            }

            $quote->getShippingAddress()->setPaymentMethod($payment->getMethod());

        }

        if (!$quote->isVirtual() && $quote->getShippingAddress()) {

            $quote->getShippingAddress()->setCollectShippingRates(true);

        }



        if (!$this->zeroTotalValidator->isApplicable($payment->getMethodInstance(), $quote)) {

            throw new InvalidTransitionException(__('The requested Payment Method is not available.'));

        }



        $quote->setTotalsCollectedFlag(false)->collectTotals()->save();

        return $quote->getPayment()->getId();

    }}

How to do this.
Thanks.
