Stuff something between the screen and the piece of plastic that has the grenadier logo, which faces forward.
You need to either create more gap(so the two surfaces don’t make contact) or fill the gap with something sound deadening.
Yep, the fix from
@HereinDaRockies is the magic needed to stop the creaking. I did the same fix. I don't have a photo and the docs portal is not playing nice for me today so I cannot pull up a diagram

.
The silver trim piece behind the infotainment screen has a long flat back. It's this section which chafes against the back of the infotainment screen housing after a bit of heat and dust. That's the glorious creak sound. If you want to test it slip a business card or a similar thin non-plastic thing under the top edge. That should be enough to separate the surfaces and stop the noise temporarily. You might need to try this in a couple of spots.
This was my typically over-engineered fix:
Pop the silver trim piece off. Ends first then the back. The ends move outwards away from the screen like you're turning a U into a V. Today you're a Master Trim Whisperer. Go gently now. This is thin trim and should not need tools.
If you don't have a standard compliment of three hands and the ends are fighting you while you unclip the back, slip some business cards under the ends to distract them while you ease the back out.
With the trim safely in one piece on your bench

, apply a narrow (~6mm/0.25") strip of thin tape inside the top and bottom area of the back section. Study how the trim fits on and put the right amount of tape on the obvious contact areas. You're aiming to have the tape separate the plastics. You'll soon know if you nailed it. Less is more. If you use tape that is too wide or too thick it will stop the trim from fitting correctly.
Any thin tape will suffice. As a guide, plastic electrical insulation tape might be too thick. I used some strips of Tesa 4661 cloth tape because I have it in my toolbox.
Double sided tissue mounting tape is a viable option but test it with the outer backing paper left on. You're not trying to glue the trim in place (or are you?)
You could probably use masking tape/painters tape but it may wear through after a while.
A gutsy packing tape or cellulose tape might be ok but they're plastic so results might vary.
...etc.
