The Kenevo Expert 2023 runs a RockShox Boxxer with a 20x110mm Boost front axle, which is the same standard as the Zeb — so you won't need an adapter at all. The Zeb is a straight swap in that regard.
Worth confirming the axle diameter and spacing on your specific wheel before pulling the trigger, but 20x110 Boost has been the Kenevo standard and the Zeb supports it natively.
The main thing to double-check is the brake caliper mount. The Kenevo runs a 200mm front rotor on a post mount, and the Zeb uses the same post mount standard, so that should carry over without issue too.
