Coffee Lake CPU In Dell Sky/Kaby Lake motherboard? (Dell Optiplex 7450) possibilities

I was excited to hear that people here successfully got Coffee Lake to work in Skylake/Kaby lake motherboards.
From what i’ve read it seems for the most part like these are like the gaming style motherboards from DIY built computers.

But can anyone point me to a method to get Coffee lake cpu working in a Dell Pre-built system with Skylake/Kaby Lake motherboard? Dell Optiplex 7450
