Focus Screens and AF Confirmation Chip for Manual Lens

[AnnaMc]

Hello!

I have a Rebel T100 and I'd like to try the manual Rokinon 85mm F1.4 Aspherical Lens (Canon EF mount). The reviews for the lens mention using an Ee-s focus screen and installing an AF confirmation chip on the lens. My two questions: 

1. Can the focus screen be replaced on the Rebel T100?

2. Is there some sort of adaptor that I can use that already has a the AF confirmation chip built in? Or is the best route to glue the chip to the lens as I've seen in the YouTube videos?

Many thanks!

Are you sure you have a Rebel T100, I can't find such a model on the Canon site?

Pretty sure that none of the Digital Rebels have a user changeable focus screen.
