Electronic – how to prevent short circuit between thermal pad and vias on it as it is recommended that exposed pad should not connect to GND

altium

All my QFN footprints are made with the Altium internal "Tools -> IPC Compliant Footprint Wizard". I get nice footprints with vias in the thermal pad.

When I try to place one of those footprints to the PCB, I get an short circuit violation between the via and the pad

but it shows the error as mentioned below

It is recommended in datasheet that exposed pad should not be connected to GND

let me know if allowing the short circuit in design rules is ok or is there any other way to solve it.

Change the designator of the vias to be the same as the pad, i.e. 25.

Then, go ahead and add a Net Label to the schematic for its pin. Altium doesn't like it when things don't have net labels.

Here in my case the pin is named GND, but it's currently not connected to anything. You should no longer have short circuit violations in your PCB.
