Making units invisible via trigger

I was just wondering if it is possible to make a unit invisible without using any abilities. Can it be done using triggers alone or not? Thanks!

why not use any ability?

I was just wondering if it could be done without using abilities, I don't actually need it though. Can it be done or not?

No, it cannot be done without abilities.

Thanks Vexorian, I was just curious about that, sorry if i wasted time. + rep

Ohh I think it can.
What about Animation - Change (Any unit)'s vertex coloring to (100.00%, 100.00%, 100.00%) with 100.00% transparency

Holding alt shows life bars. And they can still be selected. So kind of, but not really invisible.
