Keychron V6 Max - any way to make it wake up from sleep instantly, aka Logitech Lightspeed?

I'm coming from a Logitech G613, which has served me well for around 5 years, but switches started to systematically fail, plus I wanted something less gaming-oriented anyway. Seems like for my needs (100% layout, removable switches, 2.4G wireless, as few additional macro keys as possible, sub-$150) the V6 Max/Ultra is literally the only board that fits and is available where I live.

The G613 has one extremely cool feature that I got addicted to, though - it's extremely aggressive at saving battery (as in, goes to sleep after 2-3 seconds of inactivity), but makes up for it by waking up literally instantly and registering the first press. As in, there's no difference in using that vs a wired board in terms of waking up from sleep, I don't even notice it's sleeping. And it makes its 2x AA batteries last many months.

Is there a way to achieve the same effect on a Keychron wireless board? Only asking because Keychrons have open-source firmware, so maybe battery management can also be tweaked. Alternatively, how much can the battery last if I turn off sleep at all (with RGB turned off, 2.4G mode)?

If it's not possible, unfortunately that's a deal-breaker and seems like my only option is to seek out another brand new G613.
