Safe removal of preboot drivers in the Drivers Database Management

I was looking to remove a number of out of the box preboot drivers under Driver Database Management and leave drivers that only pertain to the Dell Optiplex/Latitude models I deal with. Removing any drivers, will have impact on anything else but WINPE and Linux PE? Myself and my Administrator are not sure if these drivers may affect anything else in Altiris we may not be aware of. We are running 7.5 SP1.
