Compass in flight reset

Hi people.
Is it possible to switch off compass reset in flight?
I tryed all params about- nothing help.
It looks like this function not work or I miss something.
4.3.5 and 4.5.0 -no difference.

I have bad GPS here so it’s impossible use it and mostly I fly in Althold.
After “GPS or Compass glitch” I have “compass emergency force reset, yaw realighned, Althold”.
After that compass show me 193 deg instread of 40deg before glitch.

I want make 100% thrust to compass.
Compass heading only.
Let GPS will be good option for me.

RM-3100 compass work well.
After Compass-Motor calibration interference 27-30% @ 90% throttle.
Additionaly I increase X-axis correction and now during maneuring I have compass accuracy +/- 1 deg in all flying directions at full throttle.
Thanks to all.
