Issues with RST - Intel Rapid Storage Technology

So last spring I tried installing Mint on my Dell Laptop XPS15 and ran into issues and decided to let it go as I had other things to take care of. I’ve been using my Dell Optplex desktop with Ubuntu with very few problems and love it. Decided to try to install Ubuntu on my Dell Laptop XPS15 and got the message that I need to turn off RST.

Looking at others questions, it looks like there are two options that have been discussed. I used to be pretty good at technology stuff, but my aging brain doesn’t process like it used to. @vasileios , any chance you might be able to walk me thru my newest challenge?
