With DDEV, I'm developing with Laravel a project and I use Sqlite for local so I don't really need a proper Database available.
Is there any way to take out of formula the db container completely?
My final goal is to save battery usage.
Of course. Set omit_containers: [db] in either your project or global configuration. ddev config --omit-containers=db
