How to make the second checkbox active if the disable condition is set in the first Jquery?

Question

PHP

<input type="radio" class="radio1" name="shipping_method" value="<?php echo $quote['code']; ?>"
                                       />
                            <?php } else { ?>
                                <input type="radio" class="radio2" name="shipping_method" value="<?php echo $quote['code']; ?>"
                                />
                            <?php } ?>
                            <?php echo $quote['title']; ?> - <?php echo $quote['text']; ?>
                            <?php if (isset($quote['description'])) { ?>
                                <br/><small><?php echo $quote['description']; ?></small>
                            <?php } ?>
                        </label>
                    </div>
                <?php endif; ?>
            <?php } ?>

        <?php } else { ?>
            <div class="alert alert-danger"><?php echo $shipping_method['error']; ?></div>
        <?php } ?>

    <?php } ?>
<?php } ?>

<div class="save_shipping_method active">Далее</div>

<p style="display: none">
    <textarea name="comment" rows="8" class="form-control"><?php echo $comment; ?></textarea>
</p>
<div class="buttons" style="display: none">
    <div class="pull-right" style="display: none">
        <input type="button" value="<?php echo $button_continue; ?>" id="button-shipping-method"
               data-loading-text="<?php echo $text_loading; ?>" class="btn btn-primary"/>
    </div>
</div>

<script>
    $(document).ready(()=> {


        $('#shipping_method input').change((e) => {
            if (e.target.value === 'pickup.pickup' && e.target.checked) {
                $('.save_shipping_method').addClass('active')
            }
            if(e.target.value === 'cdek.tariff_10_MRG' && e.target.checked) {
                $('#selectCdekPvz').removeClass('disabled')
                
                if(!$('.cdek_selectedPvzInfo').text().length) {
                    $('.save_shipping_method').addClass('disabled') // disabled
                }else {
                    $('.save_shipping_method').addClass('active')
                }

            }else {
                $('#selectCdekPvz').addClass('disabled')
            }
        })

        const onClickCdek = $('#selectCdekPvz.disabled').attr('onclick');
        $('#selectCdekPvz.disabled').removeAttr('onclick')
        $('#selectCdekPvz').click((e) => {
            if(!document.getElementById('selectCdekPvz').classList.contains('disabled')){
                eval(onClickCdek);
            }
        });


    })
</script>

On the site https://posezony.ru/ in the basket, the problem is that the Next button should light up when choosing the second method (pickup, aka pickup.pickup). And with the first method (CDEK), it should light up only after he selects the issue point (#selectCdekPvz).
How can I do it right? The code is not mine and I'm trying to figure it out
