LTE Passthrough DHCP change 1m leasetime possible?

I have a setup with 2 LHG R(2 different mobile provider) connected to a netgate pfSense gateway. One has a static IP, the other is on DHCP. Unfortunately the 1 minute lease-time is spamming the protocol on the pfSense and makes it quite useless.
Changing the value is not possible because it´s obviously dynamic. Is there a way to change this? I don´t want to hack the pfSense to silence the dhclient entries.
thanks
