I would like to have the Y axis units of the Power spectral densty plot show up as V/sqrt(Hz). The default way that they show up is dB/Hz

What function are you using exactly to do the PSD?

If you are using periodogram function without outputs, then it plots dB/Hz. However, if you do:
[Pxx,w] = periodogram(...);
plot(w,Pxx);
then you should get Pxx as power per radians per sample.
