If you have a 2nd gen Nest Aware or Nest Aware Plus subscription (available since 2019), you can go to the Subscription Management page (https://store.google.com/subscriptions), click on your subscription, then click on the "More" icon (the 3 vertical dots), and select "Cancel subscription".
If you have a 1st gen Nest Aware per-camera subscription (which applies only to 1st gen cameras and doorbells), I think you should be able to go to the home.nest.com website, click on your profile in the upper right corner, select Settings, then Nest Aware, and then "Manage subscription". Or you could try this link: https://store.nest.com/account/subscriptions. (Neither of these work for us because we migrated our Nest Account to a Google Account in 2020 and are on a 2nd gen Nest Aware Plus subscription.)
