Getting GPU support for a so far not supported but powerful GPU is painful and finally not possible

Most recently I have installed (and registered) PRE 2021 on my beefy i9-9900K PC. The PC has fast storage components and a powerful graphics card, the nVidia GeForce RTX 2080 SUPER. The GPU is ideal for GPU support of rendering tasks. Under "General" settings I can see 2 lines:
- "GPU has been detected" (it was my 2080 S)
- "GPU will not be supported"

What? That is more than annoying. After some googling, I found a reference to an Adobe PRE GPU beta test program that allows PRE users to test (so far) unsupported GPUs. I applied for participation as a beta tester and after entering my data I got an email with a link to a file: "PREAddGPUSupportUtility".
I thought great - and clicked OPEN. And that's when the trouble starts. I should log into my MS account:
"Sign in to xxx.com and we'll give you access immediately".
But that didn't work, the message came:
"That didn't work.
We're sorry, but xxx.com can't be found in the adobe-my.sharepoint.com directory. Please try again later, while we try to automatically fix this for you".
I tried my other MS account login but the same error. I don't have an Adobe my.sharepoint.com account and besides I don't need one I don't know how to set one up either. After some email communication with the Adobe support I received the message:
"It can only be shared through one drive. I cannot share it here".
No, I don't want to install onedrive only because of this tiny utility. What is so precious about this little  tool that it cannot be sent via easy and common ways?  
In short: IT DOESN'T WORK - and Adobe is neither able nor willing to come up with a viable solution. 
It must be in ADOBE's interest (!) that their application runs optimally. Therefore testing the influence of different hardware configurations is essential. The user can relieve Adobe of this work and become a tester himself. So Adobe doesn't have to test it itself. This is called a WIN-WIN situation.
But Adobe puts incomprehensible obstacles in the way for willing users, even though they want to create added value for Adobe. The Adobe GPU Beta Test program is much too complicated because  even participation is a massive stumbling block that I can't jump over.
