If you mean copper then yes if the calculated load is 95 amps or less. 240.4(B) & 240.6

Is the ground wire in a 2/3 romex that is copper acceptable for a 90 amp sub panel.

If you mean the equipment grounding conductor (EGC) it would need to be a minimum of #8. 250.122

The ground wire size in a 2/3 romex is a #8 stranded copper wire. Is that acceptable for a 90 amp. sub panel.
