If you are using Reaper then use the free EQ plug in
However, you can't satisfactorily remove handling noise this way because its wide band, and you will end up losing part of spectrum you want to keep, not least up there making the guitar sound dull. I inevitably cut the low end of recordings with a HPF to remove the rumble, and usually reduce the low mids but never the high end.
I usually handle issues like this with editing techniques eg setting up a volume envelope that notches things out at a trouble spot or at least makes them quieter (between position changes, it won't work over a sustained note). Learning how to crossfade neatly to join up parts is crucial too - in the studio a performer will do several takes of the whole piece and what you get in the master is basically a seamless stitching together of the best sections, that's the way I always do it now.
You might also want to try miking further away from the guitar & using coated/polished strings for recording to reduce noise.
