Here a way, I created a small shape & moved it over the white line. The I changed the color of the shape that's over the white line to match the background color. Here a demo pic;

You can do the above more simply, and without rasterising – a destructive process – by grouping the layers and using an Erase Blend Mode, see first attached image.
However, this (and the previous example) will not produce the required result as the ‘ends’ of the curve are not rounded as in the original example. To achieve that you will probably be better Breaking the curve at the necessary locations with the Node Tool and removing the unwanted parts (see second attached image).

Sorry but I don’t know what you want to achieve that has not already been shown.
I’ve attached a GIF showing another option that can be used in some cases.

thank you for helping me

While Garry´s method will end in an infinity loop path you might consider to break the "Pie" at the middle point and delete after converting to Curves:

There are many ways to do this, including one somewhat similar to what you might do in illustrator:

Boolean adding the 2 shapes automatically converts them to a single closed curve object with 7 nodes, making it a bit simpler to break it into 2 open curves & to delete the unwanted one.

The resulting open curve object can then be non-destructively rotated about its center & given whatever stroke width & cap type you want.

This great. Thank u all
