The Prime has a "B" mode on the transmission selector that increases regen.
But here's the thing: I didn't get a chance to check whether or not shifting to B
also causes the ICE to spin up (injectors off), as it does in the non-plug-in Prius.
A local salesperson has been telling Toyota hybrid buyers to use B mode to gain range when slowing, but that's a mistake because B mode ALSO spins up the ICE to increase braking. Confirmed via the RPM display on a ScanGauge. In that case, B mode wastes some kinetic energy on generating friction/heat in the engine. It's better to use 100% regen under normal conditions by just pressing the brake pedal.
However, it's possible the Prime's "B" mode may be different than the regular Prius. I'll have to check it in the future.
