Depends on how programmer will work. Normally to program a micorontroller, MCLR/Vpp has to be raised to about +13V. Usually if just usb there is a pump charge circuit, which takes 5V from USB and converts to +13V. Other programmers have a separate 13V supply which has to be plugged in. So if your programmer has a pump charge circuitry and can supply the required +13V then leave LVP disabled. Does it not say in the programmer user guide?
To try you can just load a hex file and program whilst measuring the Vpp voltage with a meter.
