How could I stabilise an aerial camera in one axis?

Question

I am refining an externally-mounted camera system for light aircraft that is attached to the wing strut, and would like to stabilise the camera in one axis so that the roll of the plane doesn't affect the angle of view of the oblique photograph.

There's a Nikon D5600 DSLR in the housing, currently fixed to the metal framework - gets good results, but as the aircraft rolls in flight the angle of view changes (it's nominally 45°). I would like to stabilise in one axis only (i.e. perpendicular to the direction of flight) - researching gimbals shows a lot of options for 3-axis stabilisation but not single-axis, and wondering what the options might be?
Can 3-axis gimbals be set to only work in one axis?

I would recommend looking at single axis solar tracker designs for the mechanical design.
These will be some form of motor connected to a plate (Where the camera could mount) that get close to 180° rotation of that single axis.
You will then want an Arduino with a gyroscope sensor like the MPU-6050 to detect the current orientation of the plane. The Arduino would then adjust the single axis motor to counteract this rotation, you may need a way of identifying the current location of the rotating axis either using an encoder or something in the mechanical design.
