I’ve seen some C4D users use a tool called Loft-NURBS it seemed like a good way to speed up my workflow.
Is there a tool in Blender to create a surface from multiple splines, but still have the ability to change their shape?

Loft-NURBS in Cinema4D
In blender this is called Skinning:
The image included in the question shows a shape with a differing number of segment points. This is currently not possible.

Note. There's work being done to give Blenders limited NURBS a overhaul (but progress has been slow).
Yes you can. It is in an addon under Add Curve called Curve Tools.

Add some curves to the scene..

Then press Loft

Once you are finished, a mesh is made separate from the curves so you can continue editing or tweaking them.
There Are some geometry tools built into Blender now which have some basic functionality similar to lofting.
(Curve) / Properties / Data / Geometry / Bevel
The problem is it only seems to allow a single primary shape plus a taper shape to generate the geometry along a path. I cannot see a way to implement more shapes like you can in other software where you could add dozens of different shapes to transform between.
However one of the key features of Lofting is the ability to generate your geometry along a path which might be rather intricate, and Beveling a curve allows you to do just that.
By using curves (splines) either bezier or Nurb you can assign another curve as a Bevel Object which is then applied as geometry along the base curve. There are options to Cap and Taper. see documentation: https://docs.blender.org/manual/en/latest/modeling/curves/properties/geometry.html
