@vitexo87 You need a Rank Measure and then add that Measure in the Visual Level Filter as in the picture...
then in the Visual Level Filter select => is less than and type 11 (to see the top 10)
After you've sorted your top ten issue, please consider using a different chart type. Pie charts, specifically 3D pie charts are very bad choices for data visualisations. Humans cannot easily compare wedges of a slice, and a 3D distortion makes it even more difficult.
With two or three data points, a pie chart is fine, because the differences are still easy to see, but for more than that consider horizontal bar charts, sorted by value.
For a more comprehensive discussion about alternatives to pie charts please read Save the Pies for Dessert by Stephen Few.
To get your rank, you should be able to use the documentation for RANKX:
Or for EARLIER

I shall add to the @Sean solution. If we can put an if condition and give default Rank value to all ranks more than 10 to not disturb the proportions on pie chart. Since its visualisation and pie chart shows proportion, seeing only top 10 over whole pie can interpret different proportions.
@achinm45 That is another reason not to use a pie chart in this scenario. A horizontal bar chart does not need to add up to 100 %, whereas in a pie chart, showing only part of the data distorts their absolute value, there would have to be an 11th data point summing up all "other" data.
I tried to do exactly as your example, the number of values being presented is more than 10, I took one print, where is the error?
Top 10 Suppliers Purchase Order = CALCULATE (RANKX (DMEGF_Fornecedor; sum (Facts [Vl_PedidoCompra]);; 0; Dense), ALL (Facts [Vl_PedidoCompra]))
can you try the example below?. and make sure you replace your measures and Dimension
InternetTotalSales = SUM( InternetSales_USD[SalesAmount_USD]) // replace with your measure here
BottomRank = RANKX(ALLSELECTED('Product'[ProductName]),[InternetTotalSales],,ASC,Dense)
BottomSalesByProduct = IF([BottomRank] <= 10),[InternetTotalSales])
then add the last measure to your chart
