Why would you not use them? There is no direct option to switch
them off in the Gromacs code; it would require you to manually
adjust the chargegroup definitions in your topology file(s)...

Having said that, it does seem that in PME, where there is no real 
cut-off from interaction to nothing, the notion of using chargegroups
seems superfluous...
