Unfortunately you can't.
Round ends and that is it.
You can use zero height walls for your lines but then you can't make them dashed without stopping and starting yourself.
I tend to set a limit for pen thickness I use for lines to 0.5mm maximum.
Just thinking you could maybe make a custom symbol line type by placing some lines close to each other (not to close).
I'm sure I have read this here somewhere before.
Be sure to use this line with a thin pen (but thick enough to blend the lines).
If too thick a pen when using this line it will still have curved ends.
