What about on cars that don’t have the air suspension?
Does it change the AWD system, or simply starts de car in second gear?
I think it would engage AWD, sending more torque to the rear. On T8, it starts the gas engine immediately at least.

What does it actually do?
OFF ROAD
• Maximise the car's traction when driving in
difficult terrain and on poor roads.
The drive mode provides high ground clearance,
steering is light, all-wheel drive and the function
for low speed control with hill descent control
(Hill Descent Control) are activated. Start/Stop
function is deactivated.
The drive mode can only be activated at low
speeds and the speedometer shows the range
for speed limitation. If this speed is exceeded, Off
road mode is suspended and another drive mode
is activated.
In the Off road mode the driver display has a
compass between the speedometer and tachometer

Back to my original question, what does “Maximize traction” actually mean? Does it dynamically change the torque to where it is needed? Does it start at a higher gear? Does the gear box and acceleration mapping change?
Making the steering lighter does not help traction and having a compass in the dashboard is a joke...

Contact Volvo USA for these explanations

Volvo has nothing like this:

I was hoping that some of the old timers and studious folks in this forum may know what their car is really doing.
Only someone who works at Volvo can know, of course, as gearbox and engine technician
What Volvo thinks by the term "Maximize traction" is known only to them

I won’t claim to understand the changes in off road but there are some videos showing the off road mode.

My experience with the Hill Descent Control is that is very helpful but regarding traction, I couldn’t experience any difference compared to Constant AWD.

Constant AWD is for T8. On T6, we are just not sure how much torque is distributed to rear in offroad mode. Is it the max value 50%? We don't know, don't see it specified anywhere.

Check out https://www.volvocars.com/en-th/support/manuals/xc60/2018/starting-and-driving/drive-modes/low-speed-control
At low speed:
- spin control characteristics change to improve traction where spinning occurring is helpful (sand / loose surfaces)
- greater bias to AWD

My own experience is that Volvo's system is pretty well sorted even in Gen 2 Haldex guise with wheels off the ground / in sand (with DSTC disabled). Its now Gen 5 and better.

Some VW(Audi) and Landrover Discovery Sport use this system.

Try https://www.caradvice.com.au/videos/top-10-suvs-off-road-which-medium-suv-is-the-best/ to see some how much systems can vary. (even a Tiguan for the Audi lovers :).
