My 2018 1500 requires a Bypass Cable
According to KaodTech 2018 requires the bypass cable

I have a 2022 Durango R/T. It uses a bypass module rather than the cable that Rams use.
This is the one I use. It works well with both AlfaOBD and Jscan. It also works with my scan tools, but since they are set up with a FCA AutoAuth account, it's moot.
It fits the 2018 and up Durango and Grand Cherokee.
2018+ Security Gateway Bypass Device
This device is required to program 2018 and newer Chrysler, Dodge, Jeep, and RAM vehicles. Our Bypass Device connects the wires between the security gateway module and the vehicle’s computer. Security is then deactivated, and the OBD Genie can be installed.
In the dropdown, select C-MODBYP - Best for 1500/Classic Body
The gateway module and harness are under the passenger side foot area, left side.
There are a few videos on youtube that'll show you where to find it. Two connectors.
DiabloSport 2018+ Dodge Durango & Jeep® Grand Cherokee Bypass Module Installation
In this video, we show you how to install the bypass module needing for tuning on the Jeep® Grand Cherokee and the Dodge Durango.
AFAIK, the 5th gen 1500s have the SGM behind/beside the OBD2 port, depending on the year.
My '21 Warlock has the SGM behind the radio which makes the KaodTech harness preferable.

He was asking about a 2018 Jeep Grand Cherokee. I'm pretty sure the module is in the same place on all of the Durangos and Grand Cherokees from 2018 up to the current models. Maybe.
