Ramos, 35, has not featured since picking up a calf injury in March.
Real boss Zinedine Zidane said: "We've got our leader and our captain with us. I won't be taking any risks. Sergio is here with us. That means that he's ready to play, that's all it means."
Los Blancos are chasing a 14th Champions League title and their first final appearance since 2018.
