To increase the quota, you can submit a request through the Azure portal:
- Sign in to the Azure portal.
- In the left menu, click on "Help + support".
- Click on "New support request".
- Select the "Issue type" as "Quota".
- Fill in the required information, including the subscription, the resource type, and the new quota limit you're requesting. Once your request has been reviewed and approved, the quota will be increased, and you can proceed with creating the resources using the custom template. Regarding reverting the quota increase, it's important to note that quotas are in place to ensure fair usage of resources across all Azure customers. If you find that you no longer need the increased quota, you can submit another support request to decrease the quota back to the original limit. However, it's not mandatory to revert the quota, and you can keep it as long as you don't exceed the allowed limits for your subscription.
