Unlikely. NCO implements simple modulo integer arithmetic. The given constant will result in an excact output frequency of 10e3*25769804/2**32 = 60, within the accuracy of the crystal generating the 10k input frequency.
Ignorant question, how do you determine "phase drift over time"? Comparing with mains frequency? Then you'll likely see a "drift".
P.S.: I presume that "drift" doesn't mean the phase jitter of one input clock period.

Yes I am comparing it with mains frequency. No not the jitter of the one input clock period. The phase of the nco constantly drifts one way or the other. If I increase the frequency of the input clock the drift increases in speed.
