6470b Bs 11.7 and Monterey 12.6 Hd4000 no brightness slider

[mkdj77]

Hi since last 2 3 years I'm using my ProBook 6470b for my DJing/live music perfoming installed mac using your clover package creator Thank for your awesome work... @chris1111

Currently i have Monterey 12.6 running on 6470b (i7 3520m) pre install check and testing... For moving from high Sierra to Monterey (would love get suggestion big sur or Monterey?)

Monterey is running good (nice hd 4000 patch bro @chris1111 ) so far but i don't have brightness (so far my main concern is that)
No brightness slider in sys pref. also
Please help me get past this issue
I need Max perfomance out of my 6470b because this is the only thing i have for making music and perfoming at stage

Cpu : i7 3520m
GPU : Hd4000 (qe/ci working with hd4000 but no brightness control in sys pref and control center)
