Things like inverse arp are used for L3 -> L2 mapping. (the output of "show
frame map")
The question revolves around "show frame pvc" and the short answer is that
there is no way to make anything disappear from that. DLCI values there are
given to you from the frame switch, and the frame switch's configuration is
static and out of your control.
The fact they are showing up unused is just fine, although if you are in a
physical-only interface configuration, you may find you have extra active
PVCs. This is one of the catches of the CCIE lab. The idea is not to use
them. If you aren't mapping anything to those DLCIs, for the most part they
just sit there.
But the concern should be with output of the "show frame map" command, not
the "show frame pvc" as far as their mere existence!

Well there are a couple of ways.
1. no frame-relay inverse-arp under the interface or subinterface - would
stop them in their tracks - may require a reboot to get rid of existing
maps.
2. clear frame inverse-arp - is a commonly discussed method but does not
seem to be 100% effective.
3. Some recommed to change the encapsulation type and then change it back.
Personally, I like option number 1
