How to separate two elements within a grid, with a BoxView? - xamarin.forms

Question

I have a ListView that contains a grid with some Labels, I want to put a separating line between two labales, but in doing so I have to indicate to the BoxView in what row of the grid it should go, and in doing so, the BoxView covers the entire size of the grid. line, is there any way that only a thin line is drawn and not the thick blue line?
