jquery, как отключить autofield в input

у меня есть форма, и я хочу в ней отключить автозаполнение.

я перепробовал много вариантов, типо таких как

autocomplete="off"

Использова как и в <form autocomplete="off"> так и для input, ничего не помогает.

серавно появляется список и автозаполнение срабатывает. Подскажите, как от него избавиться?

<form id="request-help-step1-form" autocomplete="off">
    <div class="row">
        <div class="col-md-12">

            <div class="device-type-section">
                <input id="dt1" type="radio" name="deviceType" value="Other Media" checked>

                <input id="dt2" type="radio" name="deviceType" value="Hard Disk Drive">

также я пытался использовать jQuery и disableAutoFill(), но оно также не помогало
