Both families register a SET command that the spec never described, so a YNL client could not modify an existing datapath or vport. The kernel handlers take CAP_NET_ADMIN through GENL_UNS_ADMIN_PERM. Datapath set changes user features, the masks cache size and the per-cpu upcall pids. Vport set changes the upcall pid; the kernel rejects a type change and rejects options.
