M18 annoying fan Noise in Quiet mode.

I have an M18 R1 i9 13890HX and a RTX4090 the Laptop is a beast can get up to 36700 in Cinebench R23 so in term of efficiency and cooling there is no Problem, however when I use the laptop in Quite mode the two main fans start at 55C and run at 75% speed for 5sec and then at 35% speed for around 15 second which produce an annoying sound with whistling That I can't tolerate any more. please help I can't find any fan modification possible in the bios to at least stop from running at 35% speed Alien FX doesn't work either no fan curve fixes this problem same about the AWCC I'd prefer 20 sec with 50% than the 15 sec with 35% speed. Please Help appreciated.
