Is that possible if I want only 2 tb iCloud and Apple TV ?

Hello,

You can purchase subscriptions for multiple Apple services, anApple One plan, or a combination of Apple One and specific service subscriptions. Its up to you to determine which would be better for you.

For example:

TV+ ($6.99) and 2TB iCloud+ ($9.99) = $16.98

Apple One Individual ($16.95) + 2TB iCloud+ ($9.99) = $26.94 This will include 2TB and 50GB iCloud+ storage, TV+, Music, and Arcade.

Apple One Premier = $32.96 This will include 2TB iCloud+ storage, TV+, Music, Arcade, Fitness+, and News+.

If you wouldn't use any of the extra services in an Apple One subscription, subscribing to the two services individually seems to be the best value.

How to switch to a different subscription plan - Apple Support

Apple One - Apple

Apple TV+ - Apple

I hope this helps.
