Transparency gradient on arc LVGL V8.3

Hello, I am using LVGL V8.3.

From this post Color gradient on arc, I understand that it is not possble to have a color gradient on the ac, as for example, we can find in colorwheel.

Is there any way to set an opacity gradient on the arc, e.g. asif I’dd like the tail of the arc to get transparent at some point.

Thank you,
