Answer 2

I have checked all the way... but seems currently it not show me anyway to add htmlclass in tab.

I have checked

vendor/magento/module-ui/view/base/ui_component/etc/definition/ui_component.xsd

which only allow below attribute to filedset

 <xs:attributeGroup name="ui_element_attributes">
 <xs:attribute ref="name" use="optional" />
 <xs:attribute ref="template" use="optional"/>
 <xs:attribute ref="component" use="optional" />
 <xs:attribute ref="class" use="optional"/>
 <xs:attribute ref="provider" use="optional"/>
 <xs:attribute ref="sortOrder" use="optional"/>
 <xs:attribute ref="displayArea" use="optional"/>
 <xs:attribute ref="extends" use="optional"/>
 </xs:attributeGroup>

so you can make custom js and hide the tab like below:

 jQuery("#tab_general").parent('li').hide();
