The setting is called fog light dropout. Set it to no and the fogs will stay on with high beam.

P.S. 18Crew - you beat me to it.

Did you figure this out?

It should be in the body computer CBC fog light dropout enabled. Change to disabled and it will leave them on with high beams.

Did you figure this out?

Yes, it was the fog light drop out function, as others mentioned

The real issue I was having was that this is a 2018, so I needed a security gateway module bypass cable which NO ONE makes for a journey

So I took a change on something marketed as a 12+8 cable, and it works like a charm
