Alter DHCP Lease times

Please add the functional ability to alter the LAN DHCP IP address lease time.

I just unboxed and setup a brand new Nighthawk AX 12 - RAX120.  Went to change the lease time for DHCP IP addresses and, nothing!  I bought this router to upgrade from a Linksys that was limiting my ability to manage so many IP addresses - it, at least, gave me the option to change the IP address lease time.

Seeing as Netgear is marketing this device as the answer to so many connected clients, the fundamental ability to alter DHCP IP lease times should be included.
