Set QLI Field ReadOnly but not working in Create View

Hi All,

I'm trying to display a custom product field in QLI, So I made necessary changes. This particular field "total_number_c" should be a ReadOnly in QLI, So I made the following change:

src/custom/modules/Products/clients/base/views/quote-data-group-list/quote-data-group-list.php

array(
      'name' => 'total_number_c',
      'readonly' => true,
      'label' => 'LBL_TOTAL_NUMBER',
),

 src/custom/Extension/modules/Products/Ext/Vardefs/total_number_c.php
<?php
/**
 * Total Number - custom db field
 */

$dictionary['Product']['fields']['total_number_c'] = array(
    'audited'                   => true,
    'calculated'                => false,
    'cols'                      => '',
    'comments'                  => 'Total Number',
    'default'                   => '',
    'dependency'                => '',
    'duplicate_merge_dom_value' => '0',
    'duplicate_merge'           => 'disabled',
    'help'                      => '',
    'len'                       => '255',
    'massupdate'                => false,
    'merge_filter'              => 'disabled',
    'name'                      => 'total_number_c',
    'no_default'                => false,
    'reportable'                => true,
    'required'                  => false,
    'rows'                      => '',
    'size'                      => '255',
    'source'                    => 'custom_fields',
    'studio'                    => 'visible',
    'type'                      => 'varchar',
    'unified_search'            => false,
    'vname'                     => 'LBL_TOTAL_NUMBER',
);

Dependencies: 

Note: This issue is not occurring if we remove the dependencies below.

src/custom/Extension/modules/Products/Ext/Dependencies/magaging_business_rules.php

<?php
$dependencies['Products']['magaging_rules'] = array(
      'hooks' => array("edit", "view"),
      'trigger' => 'true',
      'onload' => true,
      'actions' => array(
                                 array(
                                       'name' => 'SetRequired',
                                       'params' => array(
                                             'target' => 'total_number_c',
                                             'label' => 'LBL_TOTAL_NUMBER',
                                             'value' => 'isInList(related($quotes,"managing_c"), createList("one","two"))',
                                       ),
                                  ),
                                 array(
                                       'name' => 'SetVisibility',
                                       'params' => array(
                                             'target' => 'total_number_c',
                                             'label' => 'LBL_TOTAL_NUMBER',
                                             'value' => 'isInList(related($quotes,"managing_c"), createList("one","two"))',
                                       ),
                                 ),
               ),
);

With the above changes, the field is ReadOnly in Quote Record view / Edit View but during Quote create the field changes to an editable field. Refer to the image below.

Quote Edit View:

Quote Create View:

If the QLI was a subpanel I could create a create-view-subpanel to solve this issue, but I'm not sure how to make the field read-only.
