i think you could disconnect the tamper wiring from the pcb inside the main unit but this will disable all the tampers on all the sensors in the property.there is also a tamper switch on the main unit cover and any extension key pads attached

If it is showing Tamper you can not isolate when setting, that's not how alarms work, it needs repairing correctly.
