You do not need to use a dedicated gluten-free oven, however here are some tips to prevent cross-contact:
Avoid cooking gluten-containing foods and gluten-free foods together in the oven - do it separately.
Make sure to clean any surface your food will touch before using the oven. Place food on a clean pan or use foil. Make sure the wire shelves are free of crumbs if cooking directly on the rack.
Also, do not use the convection feature when cooking gluten-free because there might be flour in the fan from when regular bread/food was baked that can recirculate and potentially cause cross-contact with gluten.
