No , ref Pitch and ref note are global settings. They are only related to the scale you are using, making them per-oscillator would not be sensible.
A parameter that could in theory be set per oscillator is the middle voltage. This would basically give You the ability to offset the output voltage.
A much better approach though is to use the vco’s tune pots to put them all to roughly the same pitch (when they have the same input cv)
