I am running two one-way nested domain (D1=15 km and D2=3 km) with WRF Solar model. According to the benchmark WRF Solar configuration, the cumulus scheme needs to be turned off and use the Deng Shallow convection (shcu_physics =5). D2 is running in Convective Permitting Mode, should I turn off the Deng Shallow Convection scheme for D2?
 
It is not clear if it should be turned on or off. You can take a look at this article that points to positive impacts of activating the parameterization at 3 km grid spacing:
