Let 1g = 1 c per year = 9.4998 m/s².
 To keep the coordinate acceleration a equal to  1 g
the proper acceleration A must be:
at t = 0   year   A =   1.00 g
at t = 0.8 year   A =   1.65 g
at t = 0.9 year   A =   3.33 g
at t = 0.99 year  A =  33.4  g
at t = 0.999 year A = 333.5  g
at t = 1.000 year A = infinite

 No.
 It's not the current problem.
 at t = 0   year   A =   1.00 g
 at t = 0.8 year   A =   1.00 g
 at t = 0.9 year   A =   1.00 g
 at t = 0.99 year  A =   1.00 g
 at t = 0.999 year A =   1.00 g
 at t = 1.000 year A =   1.00 g
I beg you to understand something:
in the rocket's frame of reference, the acceleration is constant.
The motors are manufactured to give a constant acceleration of 10m/s² (a=1.052ly/y²) and there is no need to look for rabbit crones.
Certainly, in the terrestrial reference frame, this acceleration will appear to gradually decrease over time and this will give the following equation for the acceleration observed in the terrestrial reference frame:

But in the framework of the rocket, built for that, there is no need to make any unnecessary modifications.
