Creating a Template Spec with the Azurem Provider

I am looking to use the Azurem provider(v3.7.0) to create a template spec but as far as I can tell I am only able to create deployments from a template from the documentation.

I had tested with azurerm_resource_group_template_deployment, which of course created a deployment, but I am looking to just create a template spec for a specific resource group for use at a later date and not actually deploy anything. Is this something that the Azurem provider has the capability to do?

Thanks!
