Hi Gino,
I’m not certain if the math will be the same, e.g., getting the same results.
If you create a Spline you have access to several interpolation options.
A “Cubic-Bezier” is not available, only a Bezier or a Cubic, besides Akima and B-Spline (and of course the obvious: Linear).
You can create an empty Spline: Main Menu>>Create>Spline>Empty Spline.
This will be the Container for your data.
While the Empty Spline is selected in the Object Manager, you can select in the Attribute Manager the Interpolation.
With the Object selected, go to the Structure Manager, and there request a new entry, which you can do here: Structure Manager>> File>New Line. Repeat this for each new point.
Perhaps start with a few points to see which interpolation method will work, if it is at all congruent.

If you are savvy with Python, you might have an option to access the document with your data and use the content to convert it to a curve, if a different math is needed.
I saw a dissertation about a method / plug-in from 2013, from Bonn, Germany, but I’, not aware of a public availability. Perhaps search in Google as well, you might know better what works.
All the best
