The idea I like best would be to install a switch (or even a variable resistor to adjust amount of assist) by the trunk button where it would be very simple to turn eps off and on for whatever driving conditions you were in or whoever was driving.
Is there a convenient wire that could be used to perform this function? I was thinking it could be the wire for the strain gauge sensor so that you could just interrupt the signal and the whole system could still be on, but just not doing anything because it thinks there is no steering force it needs to counteract. Not sure about the intricacies of the system, is that feasible?

I would start by pulling the fuse. You will quickly find the FR-S is not a Malibu. The FR-S ratio is 13:1 vs 16.4:1 on the Malibu. With EPS disabled the FR-S is incredibly hard to turn even while rolling.
It’s the #46 fuse in the engine compartment. It’s 80A for a reason. It takes a ton of power to manhandle the tight steering rack.
