The easiest way is to zoom way in on it - if you can see pixels, it will only engrave - if it stays smooth no matter how close you get, it’ll cut/score/engrave.
This is opening an .svg in my browser and zooming in 500%.
Eg.
The red line is a vector, the wood grain is a raster.
So the red I can cut/score/engrave, the wood I can only engrave.
