Stop autofill email address on checkout page while selecting any fields from suggestion

I need to stop autfill of email address field on checkout page.
When I enter any address, Some suggestions are coming and selecting the suggestion some fields are autofill. So, I need to stop autofill of email field.
I have already try autocomplete= “off”, but this option not working for me.
Can anyone give suggestions on this issue?
Thanks

The autocomplete it’s done automatically by browser based on your data and it’s done based on your action.

The autocomplete=“off” you mention have a different actions and it’s only for the active field, the one that you are updating in that moment

Try creating an override of the design/themes/responsive/templates/views/checkout/components/profile_fields/field.tpl template, where replace the following code:

    {else}
        <input class="litecheckout__input{if $field.class} {$field.class}{/if}{$input_meta}"
               placeholder=" "
               id="{$field_id}"
               type="{$type}"
               name="{$field_name}"
               value="{$field_value}"
               data-ca-lite-checkout-field="{$field_name_helper}"
               data-ca-lite-checkout-auto-save="true"
               autocomplete="{$field.autocomplete}"
               aria-label="{$field.description}"
               title="{$field.description}"
               {$field.attributes|render_tag_attrs nofilter}
        />
    {/if}

with this one:

    {else}
        <input class="litecheckout__input{if $field.class} {$field.class}{/if}{$input_meta}"
               placeholder=" "
               id="{$field_id}"
               type="{$type}"
               name="{$field_name}"
               value="{$field_value}"
               data-ca-lite-checkout-field="{$field_name_helper}"
               data-ca-lite-checkout-auto-save="true"
               autocomplete="{$field.autocomplete_type}"
               aria-label="{$field.description}"
               title="{$field.description}"
               {$field.attributes|render_tag_attrs nofilter}
        />
    {/if}

I hope it will help you.
