They can't void your warranty because of it, they can however deny your claim on that system and refuse to fix anything tied to that part.
It is safer to have your dealer install the parts but not necessary. If you do it yourself or have someone else do the job, your dealer can deny any claim tied to that part because of "incorrect installation by the 3rd party" and tell you to take it up with them.
