Hi Chris - If I'm following you right, you have a PV system on a detached garage that ties into a backup subpanel also in the garage? The code only requires the RSID (rapid shutdown initiation device) to be on the exterior of the building. Would it work to put the RSID on the garage exterior? You could route your PV circuits to a switch or switches on the exterior of the garage on the way down to the sub it ties into. You could also use a shunt trip breaker(s) for the PV circuit(s). If for some reason you need to have the RSID on the main house, it gets trickier. Might need to trench?
