Is it possible to tell linux to look for .desktop files in a directory?

I started using rofi as an application launcher using its drun function. It works fine, .desktop files in /usr/share/applications and $HOME/.local/share/applications both show on it with no problems. I've been wanting to change where I keep my .desktop files from $HOME/.local/share/applications to just $HOME/desktop, but I can't find any way to tell linux to look for .desktop files in the directory I want. Is it even possible?
