Can I force an object to be displayed as if i had line of sight even if its behind something else ?

Hello! So I know its feasible cause I had a bug back in the days that would allow me to do it but am not sure how to do it in unreal.

I want to force an object to be always rendered and rendered last, so to force I’m to appear as if it was in my line of sight, even if it’s behind a mountain or something like that. The texture doesn’t need to be affected by light or anything, I just want that object to be always visible on screen shown in the right position (So I don’t need to see it if I don’t look at is direction) Is there any elegant way to do it?
