If they are referring to the external / public / WAN DHCP lease length that is assigned by the Comcast DHCP servers to the router / gateway device, then it can't be done by an end user. Only the Comcast system can control that. An end user may be able to control the LAN DHCP / private lease length that is assigned by the router's / gateway device's internal / built-in DHCP server to the connected network clients.
@EG ,
@XfinityRobertA _ It is the external DHCP lease length. Screen shot attached. Anything that can be done on the Xfinity/Comcast side to rectify? Thanks in advance.

Hi there and welcome to Comcast! You’ll need administrative access to your network router to be able to change these settings. While you can view the current DHCP lease time on your PC or Mac, changing it will require access to your router.

@atejwani Have you tried changing the internet release time of the DHCP address within your personal modem?

@XfinityRobertA Seriously?
"Have you tried changing the internet release time of the DHCP address within your personal modem? "
[Edited: "Inflammatory"]. Explain how a dhcp client controls the lease time on a dhcp server.

AGAIN. That is the LAN lease period that may be able to be controlled, not the WAN...
