Setting DHCP renewal time

For  R6120 router which is the DHCP server for my network what has to be done to change what the DHCP renewal timeframe is on router ?

 

Being the clients on my network are online most of the time I would like to reduce the amount of times the renewals are done per day

I find nothing in the config page in router for DHCP as to what the lease time is

so can this be changed at all ?

 

Also looking at the router log why is this always reporting often in log and how to reduce that from reporting in log ?

       Firmware version?  Connected to what?

       I've never seen a consumer-grade Netgear router which offered any
    supported way to change such DHCP parameters.

     

       But, so far as I know, the default lease time is typically 1 day
    (86400s).  See, for example:

     

          https://community.netgear.com/t5/x/x/m-p/1667716

     

       So, it's not immediately obvious that your rapid renewals can be
    blamed on the router.  Do other client devices show similar symptoms?
