2010 Prius with Pursuit 9233n alarm - problems with battery charge

We have a very low mileage 2010 Prius hatchback that is not the car for us. We travel for months away, and our 12v battery dies. We get it charged and our pursuit alarm system goes mad. And this is in a public parking garage. If anyone is familiar with that OEM alarm (thanks to our original dealer, not), do you know how to address this issue? We keep buying new batteries as at least they come charged. This is not a good cost effective solution. The Pursuit system appears to be stuck in "passive alarm" as the red valet light is flashing when the battery is charged by our garage people. Our thought is to buy another battery from AAA then try and put the alarm system in valet mode to stop the alarm going off, drive it to the dealership, and pay for the pursuit system to be removed. Then we will sell this 2010 car with 25k miles to Carnova. The hybrid Prius is NOT the car for those who are away from home 4-6 months. Any thoughts or advice? I tried posting about the pursuit alarm in 2022 and two people said to have it removed. I think now is the time, but comments welcomed.
