Disconnect Luke III Boost?

I LOVE MY EBMM LUKE III, however, have zero use for the boost. Is there a simple way to disconnect it without removing it altogether? I have the hardest time remembering to unplug my wireless after the few minutes I get to play, it sits for a period of time until I’m able to scrape a few precious minutes to play, pick it up, turn everything on and battery’s dead. UGH!

I’d just like to not have it connected, at all. Possible?
