Solution : If it helps, i've added a event in my event.xml

<event name="controller_action_predispatch">
    <observer name="addCSS" instance="Vendore\Module\Observer\AddCSS" shared="false" />
</event>

the related observer :

public function execute(Observer $observer){
    $om = \Magento\Framework\App\ObjectManager::getInstance();
    $page = $om->get('Magento\Framework\View\Page\Config');

    $condition = $this->getConditionResult();
    if($condition){
        $page->addPageAsset('Magento_Theme::css/otherCSS.css');
    }
}
