That setting is the Linux hypervisor option, not an Android “developer mode.” In Genymotion Desktop, the Settings > Hypervisor tab lets you switch between QEMU and VirtualBox, and on Linux the default is QEMU. Genymotion Desktop Global Settings

If you mean a different “developer mode” label inside a virtual device, tell me where you see it and I’ll map it to the exact setting.
