The processors in the NUCs support output in DisplayPort (DP) 1.2 format. According to this chart from Wikipedia (https://en.wikipedia.org/wiki/DisplayPort), support for a refresh rate of 144Hz is possible, but limited by the resolution that is also desired.
Now, if you are asking because you want to use one of the new monitors with 5120x1440 resolution, the answer is possibly - but not while also using the 144Hz refresh rate. DP 1.2 has a maximum effective bandwidth of 17.40 Gb/s. This monitor, operating at 144Hz, requires a bandwidth of 28.16 Gb/s. I believe that the maximum refresh rate that could be supported with this resolution is 75Hz.
Hope this helps; I am no expert in this area.
