No, he can't use it anymore because he doesn't have it anymore. He lost his sharingan when Madara stole it from him, and his missing eye got replaced by Naruto, who made him another normal one. In the battle with Kaguya, Obito was able to temporally empower Kakashi with both of sharingans that he ended up dying with. For now, Kakashi is not able to use sharingan because he doesn't have sharingans anymore, nor does he have Obito's powers. He has regular eyes.
