Do not show QuickPublish button to a some groups but publish access should not be removed.

Hi, 

You can achieve this with granite:renderconditions. You can create your own condition that displays the button only if the user is logged in with the specified user that the render condition accepts. Please check this link for a great example of how to do this: https://joao.ws/aem-granite-render-conditions/ . Once you have the render condition, you need to overlay the button to apply the render condition you created here: /libs/wcm/core/content/sites/jcr:content/actions/selection/quickpublish, make sure you don't apply your changes in that path but in the overlay.

Hope this helps

Hello @alisyed1, 
this is the exact requirement we had, We need to overlay the required node. In our case its quickPublish button, so we need to overlay it first and we need to add the  granite:rendercondition ndoe here. And in it we need to add the required property which will specify the allowed or denied groups.
Below is the sample code,

<quickpublish
        jcr:primaryType="nt:unstructured">
    <granite:rendercondition
            jcr:primaryType="nt:unstructured"
            sling:resourceType="your render condition comp."
            allowedGroups="[specify your group where we want to allow]"/>
</quickpublish>
