Probably not, the deeper you drill the more expensive it gets - exponentially. It's probably many times less expensive to use other power sources. It's not trivial so every additional hole would take great effort. Here's an article about a company that is trying to do that. https://www.extremetech.com/extreme/332693-digging-the-worlds-deepest-hole-to-extract-energy https://www.extremetech.com/extreme/332693-digging-the-world... I hope they can do it. It would be a great achievement.
