Downgrade No. Subscription on AWS Marketplace

Hi,

Need to downgrade the number of subscriptions, in Posit Workbench, which we have purchased (formerly RStudio Workbench) from Posit Software, PBC (AWS Marketplace subscription). Delivery method - Amazon Machine Image.

The subscription is on a monthly basis and it is in the auto-renewal process, and now we need only 6 subscriptions current value is 7.

Would it be possible to decrease it to 6 subscriptions in the upcoming month?

Thanks,
