Tutorial Request: Blueprint Splines, Nondestructive Splining (UE 5.7+)

Hoping to get some support here on this topic. Joined Unreal Engine earlier this Year 5.7 and have not been able to find any suitable tutorials that cover what I am looking for, which is a simple blueprint spline that is non destructive. Here’s a couple of examples. First one is destructive and will deform your landscape. https://www.youtube.com/watch?v=_NEybBdACCo&t=144s

Second one is four years old and isn’t really related to landscapes, but is a very good spline tutorial regardless because it touches on construction script. Due to the relative complexity I have not been able to figure out how to get the construction script one working, or even remotely close unfortunately because I don’t really know what I’m trying to do in that script

Ideally, would love and appreciate truly if someone would make a simple tutorial Outlining in Unreal Engine 5.7 or above, how to create a blueprint spline that use a dirt road or other road texture and can deform the terrain. Heck I would even settle for one that doesn’t deform and just works, too
