Basically, you can't.
That is the downside of having the sections/elevations generate from the 3D model.
What you model is what you see.
If you really want to, you can resort to placing a white fill over the top of what you don't want to see.
But that can cause other problems if you alter the model - the fills will not be attached to the what they are hiding and may end up hiding something else.
Easier to just live with it I think.
Actually there is one thing you can try.
Sections and elevations have a depth range.
You can set the depth so you just see the front and not what is beyond.
However, you may then end up missing part of your sloping roof.
They also have a 'marked distance' range, where the elements in that range can show with a lighter/thinner pen, so they are not so obvious.
This will also affect your sloping roofs.
I still think it is easier to just put up with it.
