Is there any way to define the mysql version before deploying?

If i deploy a mysql instance, its using mysql:9 images by default with no option to set the version. I tried to downgrade it after its started up, but get a failure message regarding not being able to downgrade unless patched version.

I guess i can deploy a docker image with mysql:8 but then it doesnt look like i get any of the setup?

Also, ive checked some of the templates, like one with backups, but they again dont show the image tag, so i assume its deploying v9?
