I could add an option to mark the quality variants as hidden, though that would make it harder to use planners (eg. upgrade planner) on them, since you couldn't manually select the quality variants then.
If you have a mod that lets you use the picker to add entities to planners ( https://mods.factorio.com/mod/upgrade-planner-toggle-entity-with-pipette ), this isn't a big issue (you can select the base entity as the target, and it will be automatically converted into the correct quality variant), but otherwise you couldn't upgrade a hidden entity to eg. another quality with the upgrade planner.
This would afaik be the only way to hide the mining drill variants from the ore tooltips.
