We use page blueprints extensively to drive automation in confluence and Jira.

Once a blueprint plugin is deployed it is available in the "Create Page" dialog for every space, however we want the blueprint to be available only to the space/s for which it is relevant.

Currently confluence supports disabling the blueprint manually for a space through Space Tools -> Content tools -> Templates.
In practical scenario there can be hundreds and thousands of spaces so disabling manually for each space is tedious and cumbersome.
We are looking for a programmatic interface to disable blueprints for spaces in bulk.
