We tried reaching you on a private message asking for the Dell PC and or Dell monitor Service Tag number to ascertain the warranty but did not receive a response. Please feel free to reply to the private message whenever you are available.
Hi AndrewShark, as this monitor model doesn't have the Linux as one of the tested OS we are unable to share the steps related to this. However, I will reach out to our product group team on this for further advise. Regarding this I will contact you via private message to collect few information.
It is sad that Dell do not cares (it seems) about sales of their products for Linux users. I personally very like the Dell monitors. But I would also like the functionality available with Dell Display Manager, speaking about auto switching Preset mode based on application in focus. Specifically, I want my monitor to automatically switch it when I do alt-tabbing from a game to the browser in which I read a walkthrough for the game (because reading text in Game preset really destroys my eyes, but playing a game in ComfortView preset is not beautiful).
I am not asking to create a Linux version of DDM. I am just asking for a documentation! Linux desktop environments are different, and each may use their own window rules etc... But we do not need your windows-specific app to arrange windows on scren. We just need a cli for controlling their monitor, and then Linux users will be able to built the gui suitable for their wishes.
I cannot see any reason to keep it "in secret". There is no anything there that other manufacturers could benefit from. But you just loose the loyalty of linux users.
So please, if you care of your consumers, publish specifications. Linux power users can benefit from it by using your products productively. Dell will benefit from it because power users will purchase Dell monitors themselves and recommend it to other professionals.
To resolve this request, it just needs to reach the corresponding department inside dell. I mean, technical support do not know what to answer because they just search in published documentation for the product in the web site (sorry, I can do it myself, but there is no this info there, at least yet). But this request could be transferred to the Dell Display Manager application team (they for sure have this info, as they implemented a windows application) and/or hardware engineers that should have this info.

For the specific problem you mention, try this:
- to switch to Game preset, set VCPDC to 0x05
- to switch to ComfortView, set VCPF0 to 0x0C
Arrived at by following Dell advice in the thread you mention, comparing the before and after values reported by softMCCS on changing the Preset mode using the monitor OSD menu.

I have found the same request (to publish the non-standard dell mccs controls) from 2018 here:

I have found several requests of dell display manager for linux:

Any feedback from dell staff please?
