It's so obvious that I wonder how you can argue with it.
Imagine your rocket at rest in a frame of reference Vo=0.6c, and another at rest in a frame of reference Vo=0.8c, accelerate the two rockets according to a=10m/s².
There is NO difference. There is no absolute reference.
It comes from this that whatever the instantaneous speed of the rocket, it is at rest in this frame of reference whatever the speed reached.
Always, and for itself, it will accelerate with a constant acceleration in the frame of reference where it will be found.
It is only for the terrestrial observer that the acceleration will be relative and that the rocket will appear to accelerate less and less quickly (it will never exceed Vo=c).

 Consider an inertial observer in space.
She has instruments like clocks and telescopes and computers,

And, as anyone can check in a GPS satellite,
they're ignoring your absurd religion and
assume t'=t.
