The product label for Ferti-lome Weed Free Zone does not mention the requirement of a surfactant/adjuvant while Drive XLR8 does the addition of one so would not recommend tank mixing them and would be best to apply separately. Not all herbicides require a surfactant as they can already contain a slight amount or adding one could reduce selectivity on turf and injure your grass.
