Hide hidden files - but just on the desktop?

Hello,

I thought I'd posted this question but now I can't seem to find it. I want
to show hidden files for every folder but one - the desktop. I can't seem
to figure a way to change this behavior for just one folder - it seems to be
all or nothing. Also - no matter how I try - even as administrator - I
don't ever seem to see the option apply to all folders - it seems to be
greyed out no matter where I am.

Thank
