I want to perform this operation between surfaces, but I can’t find the intersection, trim, or split.
Does anyone know why this happens?

Hi Fabio,
The two surfaces are virtually coincident at the left end in your screenshot. That makes it hard for Rhino to plot an intersection.
A trick you can use is to make copies of the surfaces and split one into strips using _Split with the isocurve option. Then use _IntersectTwoSets to intersect the set of strips with the other surface:
As you can see, you get the intersection you expect for most strips. At the left hand side however, you get more complicated intersections or none. Join the good intersections on the right, then go back to the original surfaces and extend the curve to the left edge. There are several options for extending the curve: in this case I found _InterpCrvOnSrf worked best.
