How to filter out overdue and unscheduled tasks?

[CavalloneChen]

due before 2021-11-04
not scheduled on 2021-11-03
is not recurring
not done
sort by priority

I would like to filter out overdue but unscheduled tasks, above is my snippet which doesn't work. Is there a way to achieve this?

Is this maybe what you are looking for? (overdue and not scheduled)

due before today
no scheduled date
is not recurring
not done
sort by priority
