Yes id be reasnobly sure the DI injectors would get damaged likely due heat if you turn them off using the pi\di tables in tune. In standard tunes your always running fuel through the DI system and i suspect without that the di injectors in the compustion chamber will get damaged without the fuel to cool them.
The stock port injectors are quite small 228 cc and dont have the capacity to run even an NA engine at high rpm full load without di., So you would need bigger ports even on NA car to run without DI.
So id say dont try to run full port unless your prepared to toast a set of DI injectors
