Using Joomla 3.9.11 and SP Simple Portfolio

When adding a portfolio item via the back end there is a description textarea field, this is required. I'd like to remove this required attribute.

Looking at the code I can see that in this location


There is the following code;

<?xml version="1.0" encoding="UTF-8"?>
    <fieldset name="basic">
        <field name="id" type="hidden" />
        <field name="title" type="text" label="JGLOBAL_TITLE" description="JFIELD_TITLE_DESC" class="input-large-text" size="40" required="true" />
        <field id="alias" name="alias" type="text" label="JFIELD_ALIAS_LABEL" description="JFIELD_ALIAS_DESC" hint="JFIELD_ALIAS_PLACEHOLDER" size="40" />
        <field name="image" type="media" label="COM_SPSIMPLEPORTFOLIO_ITEMS_IMAGE_LABEL" description="COM_SPSIMPLEPORTFOLIO_ITEMS_IMAGE_DESC" required="true" />
        <field name="video" type="url" label="COM_SPSIMPLEPORTFOLIO_ITEMS_VIDEO_LABEL" description="COM_SPSIMPLEPORTFOLIO_ITEMS_VIDEO_DESC" />
        <field name="url" type="text" label="COM_SPSIMPLEPORTFOLIO_ITEMS_URL_LABEL" description="COM_SPSIMPLEPORTFOLIO_ITEMS_URL_DESC" />
        <field name="description" label="COM_SPSIMPLEPORTFOLIO_ITEMS_DESCRIPTION_LABEL" type="editor" required="true" filter="JComponentHelper::filterText" buttons="true" />

I know that by removing the required="true" will work, but if I update the component I'll lose this?

How can I override description field so that it's not required and remains after upgrading the component?
