Yes.

Hm, technically, if the models in the ensemble support partial_fit the ensemble
method itself should also be able to use partial_fit. My guess is that it is
not implemented because it cannot be guaranteed that the individual models
support partial_fit. However, if you are using the voting classifier, you could
probably just train the individual models of the ensemble, because the voting
classifier's decision rule is fixed.
I think the following could work if the estimators_ support partial_fit:
voter = VotingClassifier(...)
voter.fit(...)
For further training:
for i in len(estimators_):
voter.estimators_[i].partial_fit(...)
Best,
Sebastian
