This feature was already requested some time ago (#116892). I would like to request it again, since I think it could be very useful to keep the task menu tidy for users that have lots of tasks (but some of them are just dependencies of other tasks). Furthermore, it would be interesting to add the possibility of sorting the tasks too, although I don't think that it is as important.

As an implementation suggestion, I think it would be great to do something similar to what it is already implemented in launch.json files with the "presentation" option, for example:

"presentation": {
    "hidden": false,
    "group": "C++",
    "order": 1,
}

The tasks.json "presentation" option affects the output behavior of the terminal panel instead, so I guess that it would be easier to call the requested feature differently (such as "menu", "menuPresentation", "menuOptions" or something similar) to avoid conflicts with previous versions.

EDIT: @herrberk, @nextgentm1, @matiasg77, @CarlPer, @mickare, @IllusionMH, @idanpa, @derekmckinnon, @omer-musa-battal, @Kirdock, @tmsampson, @HelloCore I don't know if you're still interested or you have any other suggestion.
