I keep having problems with my 2017 Lexus GX460 battery dying. I replaced the battery in April 2019 and it still keeps happening. I have to drive it every other day to keep it charged. I have had AAA here four times to charge it. I was just told by him that I should not keep my foot on the brake when I shut it off because if I keep my foot on the brake it shuts the car off but not the rest of the stuff in the car. He said my alternator was good. I need to find out why.
What makes this problem better or worse?
If I don't drive it every two days.

This is becoming a more common "concern" -- folks that don't drive enough, long enough, fast enough for a long enough duration to recharge the engine's battery. With the greater amount of electrical components draining on the battery while the vehicle is being operated, it is harder and harder to replenish a needed charge. This is definitely the first thing I would consider.
If u had aaa replace it in April it would help to find out if your car has a battery module. If so and they didn’t reset it when replacing the battery it will charge the new one as if it’s still failing. Aaa in my area has done this to 3 cars I know of and don’t seem to know about these new systems
