A government statement says Gvero made the decision after meeting with Serbian Justice Minister Zoran Stojkovic.
Gvero was a deputy to top fugitive Ratko Mladic during the 1992-95 Balkans conflict.
Mladic is still being sought to answer war crimes charges.
Gvero was not on the list of those publicly accused by the UN war crimes tribunal, but the Serbian government said it had received his indictment.
Gvero was due to travel to The Hague on 24 February.
