            </type>
<aspects>
      <aspect name="abc:Info">
         <properties>
             <property name="abc:Det">

You can use form-id to control them. To hide the field(abc:det) in the workflow details page, you can use like,

    <config evaluator="task-type" condition="abc:review">
    <forms>
         <form>
            <field-visibility>
                <show id="abc:Det"/>
                <show id="bpm:comment" />
            </field-visibility>
            <appearance>
                <field id="abc:Det" label="customproperty" read-only="true">
                <control template="/org/alfresco/components/form/controls/textarea.ftl">
                <control-param name="style">color: black</control-param>
                <control-param name="rows">6</control-param>
                <control-param name="columns">6</control-param>
                </control>
                </field>
                <field id="bpm:comment" label="Comments">
                    <control template="/org/alfresco/components/form/controls/textarea.ftl" />
                </field>
            </appearance>
        </form>
         <!-- Form configuration for workflow-details page -->
        <form id="workflow-details">
            <field-visibility>
                <hide id="abc:Det"/>
                <show id="bpm:comment" />
             </field-visibility> 
             <appearance>                               
                .....
            </appearance>
        </form> 
         <!-- Form configuration for task-details page -->
        <form id="task-details">
            <field-visibility>
                <hide id="abc:Det"/>
                <show id="bpm:comment" />
             </field-visibility> 
             <appearance>                               
                .....
            </appearance>
        </form>
    </forms>
</config>

I hope you can use, '' to configure the task-details, but I haven't tried it yet.

Update For the task-details, there is no specific form-id is used in data-form section. Refer C:\<Alfresco_Home>\tomcat\webapps\share\WEB-INF\classes\alfresco\site-data\pages\task-details.xml

  <!-- Data Form -->
  <component>
     <region-id>data-form</region-id>
     <url>/components/form</url>
     <properties>
        <itemKind>task</itemKind>
        <itemId>{taskId}</itemId>
        <mode>view</mode>
        <formUI>true</formUI>
     </properties>
  </component>

To customise this task-details form, I added <formId>task-details</formId> as mentioned below.

  <!-- Data Form -->
  <component>
     <region-id>data-form</region-id>
     <url>/components/form</url>
     <properties>
        <itemKind>task</itemKind>
        <itemId>{taskId}</itemId>
        <mode>view</mode>
        <formUI>true</formUI>
        <formId>task-details</formId>
     </properties>
  </component>

You need to use share extension / customisation best practices to change the OOTB files in share. Alfresco Share extensions

Finally in the share-config-custom.xml file add the configuration like,

 <form id="task-details">
    <field-visibility>
        <hide id="abc:Det"/>
        <show id="bpm:comment" />
     </field-visibility> 
     <appearance>                               
        .....
    </appearance>
</form>     

All set to go and it is working fine to me.
