Permanently disable alarm on 1999 Camry

I have a 98 camry alarm that goes off when I pop the trunk with the key (no keyless entry). And when I just unlock the driver door by itself. One workaround for the doors: When I unlock the driver door, I turn it AGAIN (this unlocks all the doors). The alarm has NEVER gone off when I’ve done this. Weird. I imagine you do a double button press on the fob to unlock all the doors?
