    you need to test the code like it into your functions.php of child or active theme

    add_filter( 'woocommerce_checkout_fields', 'remove_validation_from_field', PHP_INT_MAX, 1 );
 
function remove_validation_from_field( $woo_checkout_fields_array ) {
    // use unset to remove the validation from your desired field
    // like I am removing the phone number validation from billing address
    unset( $woo_checkout_fields_array['billing']['billing_phone']['validate'] );
    return $woo_checkout_fields_array;
}

    add_filter( 'woocommerce_checkout_fields' , 'woocommerce_form_fields' );
                
function  woocommerce_form_fields( $fields ) {
$fields['billing']['billing_first_name']['required'] = false;
return $fields;
}

    Actually we need use filter hook woocommerce_checkout_fields and need to modified based on billing,shiping,account,orders.
