Dhcp dns registration working.. possible to configure ttl?

tail -F /var/log/messages| grep dhcpd
Sep 29 11:55:56 xyz123-vyos dhcpd[22392]: DHCPREQUEST for ( from 84:fd:d1:d3:3d:76 (CHRMBK-5CD9318) via eth0.1024
Sep 29 11:55:56 xyz123-vyos dhcpd[22392]: DHCPACK on to 84:fd:d1:d3:3d:76 (CHRMBK-5CD9318) via eth0.1024

(dhcp working fine…)

 drill -Q -x @
 drill -Q CHRMBK-5CD9318.123.cbk.xyz. @

dns working great…

CHRMBK-5CD9318.123.cbk.xyz. 86400   IN      A

;; ANSWER SECTION:      86400   IN      PTR     CHRMBK-5CD9318.123.cbk.xyz.

Anyway to change the ttl?

set service dhcp-server shared-network-name Vlan512 subnet lease '14400'

that is the lease time

set service dhcp-server host-decl-name
set service dhcp-server hostfile-update

set service dns forwarding allow-from ''
set service dns forwarding cache-size '10240'
set service dns forwarding dnssec 'off'
set service dns forwarding listen-address ''
set service dns forwarding name-server

If any of that is relevant…

pdns_recursor docs show that 86400 is the default for packetcache-ttl and max-cache-ttl

$ grep ttl /run/powerdns/*
grep: /run/powerdns/pdns_recursor.controlsocket: No such device or address

Greatly appreciate any suggestions…
