Unfortunately, there is no option to cancel the subscription temporarily. I have checked your account and noticed that you have few remaining licenses. You can use your unused licenses as long as your membership is active, however, you forfeit any unused licenses upon cancellation of your membership. I would suggest you to download all the remaining assets before you cancel your subscription.
Also, refer Cancel your Adobe Stock membership.
You can Contact Customer Care for cancellation requests and billing queries.
Hope this information helps!
Feel free to update this thread in case of any additional query.
