En fonction de votre description, les sélecteurs suivants peuvent fonctionner :

:not(.second-stage) > :not(.second-stage) > .apply-style-here

:not(.second-stage) > :not(.second-stage) > .apply-style-here {
  border: solid 1px blue;
}

<div class="first-stage">
    <div>
        <div class="apply-style-here">Content</div>
    </div>
</div>

<div class="first-stage">
    <div class="second-stage">
        <div>
            <div class="apply-style-here">Content</div>
        </div>
    </div>
    <div>
        <div class="apply-style-here">Content</div>
    </div>
</div>
