Is it possible to modify the HK47360 servo?

Question

Arduino

Good day everyone, Guys , there is a problem namely: Mi Digital High Voltage HK47360TM
Link
with parameters:
Voltage: 6.0v / 7.4v
Speed: 0.14sec / 60deg (6.0v) -0.12sec / 60deg (7.4v)
Torque: 20.0kg. cm(6.0v)-23.0kg.cm(7.4v)
Size:40.1mm x 20.5mm x 39.4mm
Weight:61g
Gear Train: Full Titanium Alloy
Motor:Coreless They
feature a Hall effect angle sensor instead of a potentiometer.

the photos were taken by the former owner of the servos ...
in general, the essence: he has an angle sensor that is set to 90 + -5 degrees, which is naturally very lacking ...
in an unconnected state, it has free movement in any direction, it is not blocked anywhere ... is it possible to get around it somehow - give a larger angle
in advance wildly grateful ..
