How can I add a task with a due date but no due time?

(None of the topics provided when creating the question seems to "best describe" this question. So I chose one at random.) When I create a new task, I can choose a due date. But it seems that when choosing a due date, it forces me to also choose a due time. Is it possible to add a task with a due date but no due time? Maybe something akin to the "all day event" for calendar events? [https://support.mozilla.org/en-US/questions/1486606 This answer] says to "choose the option 'All Day Event'", but I don't have this option when creating a task (see attached screenshot). My workaround is to choose an arbitrary time. While this works somewhat, it's unsatisfactory. Thanks for any help.
