Move along "Arc-like" path without MoveL

Hello,

I am trying to figure out how to follow a specific "arc-like" trajectory. Say, along a quarter of a circle or an elliptic curve. Is there a way to perform such a curved move with only the start point and the end point of the arc?
I know an alternative is to increase the amount of points along the path sufficiently and use many MoveL's to approxiate the curve but I need to avoid this solution.

The path is not CAD-based, so I can't use the "auto path" function neither

Many thanks
