Remove Newsletter form Last name field from view and remove from data storage

Hi,

I am trying to remove the Last Name from the Newsletter subscribe form.  I found code in another post, and it does remove the Last Name from view, but apparently a value still needs to be added to the data storage field.  Is there a way to remove Last Name completely and not have 'NA' or '-' appended to the First Name?

This is what I have currently in the footer code injection.

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
lastName = document.querySelector('.last-name input');
lastName.value = "-";
hideLastName = document.querySelector('.last-name');
hideLastName.style.display = "none";
});
</script>

Thank you in advance for your help.

Okay, thank you.
