The Trash directory won’t be created if you don’t use your graphical file manager.
Which is likely not the route you want to go.
It simply being there doesn’t mean that something you delete can be recovered.
Just don’t put it in the trash bin in the first place.
There is always an option to “really delete” whatever.
Usually you hold down “CTRL” or “Shift” while you select and delete something
which will then be directly and permanently deleted.
You may have to first enable the presence of this option in the settings of your file manager.
But I don’t know the file manager used in LXQT and where to find that option in it’s settings.
