Uncheck my billing and shipping address are the same for store pickup

I’ve followed the instructions by creating a custom extension in the following link :
https://magento.stackexchange.com/a/361986/105485

It’s works fine, but I need it to be unchecked only when customer select store pickup.

Could you please help me with this ?

My “checkout-data-resolver-mixin.js” file:

define([
    'mage/utils/wrapper',
    'Magento_Customer/js/model/address-list',
    'Magento_Checkout/js/model/quote',
    'Magento_Checkout/js/action/select-billing-address'
], function (
    wrapper,
    addressList,
    quote,
    selectBillingAddress
) {
    'use strict';

    return function (checkoutDataResolver) {
        // Customize: Remove feature set billing address same as shipping by default
        checkoutDataResolver.applyBillingAddress = wrapper.wrapSuper(
            checkoutDataResolver.applyBillingAddress, function () {
                if (quote.billingAddress()) {
                    selectBillingAddress(quote.billingAddress());

                    return;
                }

                // The below code select default billing address as billing address
                if (quote.isVirtual() || !quote.billingAddress()) {
                    addressList.some(function (addrs) {
                        if (addrs.isDefaultBilling()) {
                            selectBillingAddress(addrs);

                            return true;
                        }

                        return false;
                    });
                }
            }
        );

        return checkoutDataResolver;
    };
});
