Hi @swaroopkumarmg ,

Base on my research, I'm afraid that currently there is no suitable visual with polynomial trendline in Power BI. You can raise a new idea and add your comments there to make this feature coming sooner. And the following one is the similar idea shared on Power BI Ideas , you can vote it up and add your comments there to improve Power BI on this feature.

Advanced trend lines in charts (polynomial, exponential,...)

In addition, please refer the following link by phython. Hope it can help you.
