Aluminum Valve Covers exist?

As the title asks, do Aluminum Valve Covers exist for the 2017-2020 Ecoboosts. I have a 2017 3.5 Ecoboost that is leaking on the driver side and have been searching high and low and can’t find any. I see some for the 2016 and below and 2021 and after.

Just figured if I’m going by to replace, I’d prefer to not replace with plastic if possible. Anyone found anything different?
