How do I completely delete Cloud Datastore from a project?

Question

I want to create a Firestore in Native mode in an existing project. I don't have any data in Cloud Datastore, but it blocks me, saying

This project uses another database service Your current project is set up to use Cloud Datastore or Cloud Firestore in Datastore mode. You can access data for this project from the Cloud Datastore console.

when going through https://console.cloud.google.com/firestore/ and

Cannot enable Firestore for this project Currently Firestore cannot be enabled in projects already using Cloud Datastore or App Engine

when going through https://console.firebase.google.com/

I've tried it with writes to datastore enabled and disabled

I just want to completely purge the Cloud Datastore product from my project.

Used to also run into this issue. But as of Jan 10, 2024 it's possible to delete datastore databases (more specifically "firestore in datastore mode" databases) from the console or CLI.
