Based on this old thread :
Based on the subscription type we have certain pricing and quota limit. You must upgrade your Azure free account to a pay-as-you-go subscription in order to increase quotas or limits.
For more detailed information on pricing and offers, you can visit the Azure Pricing page: https://azure.microsoft.com/en-us/pricing/offers/ms-azr-0170p/. To request an increase in your quota, you can do so directly within the Azure Machine Learning studio by submitting a request. Additional guidance on managing quotas can be found in the Azure documentation here: https://learn.microsoft.com/en-us/azure/machine-learning/how-to-manage-quotas?view=azureml-api-2#request-quota-increases.
For further information regarding common limits, quotas, and restrictions across Azure subscriptions and services, you may refer to this documentation: https://learn.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits.
