No.  But you aren't really designing with the Omada philosophy in mind either.

Thought #1:  The EAPs can each broadcast multiple SSIDs and map those to unique VLANs, while using another VLAN for management traffic

Thought #2:  The Omada 'way' requires an Omada gateway and Omada switch before the controller will set all of this up with isolation and magically deploy to all your devices

In your case, you can still use the controller to control the APs, as long as your router supports VLANs and you manually configure that router to support what the controller has configured on your APs.  The default VLAN for management traffic is 1 and untagged.  User traffic, mapped to subnets/vlans will be tagged appropriately.  So long as your Netgear can sort all of that out on each port that an AP is connected to, you'll be golden.
