DNS and DHCP setup help on Firepower 1010

Still learning so bear with me. I have 2 VLANs so far. For vlan 1, I would like it use DNS server 1, and for Vlan 2, I would like it to use DNS server 2. Purpose being is Vlan 1 runs Active Directory so it needs to serve as the DNS for that network for dhcp clients. Vlan 2 is for wifi and so it needs to just run opendns as the server for it for dhcp clients. I have both dhcp subnets set up for both vlans.

On vlan 1, I need its dhcp server to serve options 66 and 67.

On both vlans, I would like to be able to set static dhcp per mac address.

This was easily achievable on the small business routers but on Firepower, I am not seeing how to achieve this. I am running latest software version on the router.

Does this require using flexconfig?

@EvanC75 unfortunately using FDM (even version 7.2) all DHCP scopes use the same DNS server(s). You'd have to run DHCP on another device other than the FTD to achieve what you require.

I see, is the same true if I ran it through FMC?
