LMX8410L: PIN Function

Part Number: LMX8410L

Hi, I am in a design process and I need this IC, I have a question about PIN 34 and PIN 37. The datasheet shows different pictures with those NC PINs (top view of the package, block diagram) even typical application; however, the pin functions table shows that those pins should be connected to IF ground. Also, I saw from the EVM board schematic that those pins are effectively connected to GND.

If we let those pins float, can they do any damage or generate some kind of short?; what would be the recommended configuration?
