I have not used an M60, but for stress testing (thermals / power) I like to use the Folding @ Home client, which tends to max out GPUs pretty reliably. The client is officially for Windows 10 / 11, but I assume it would also work with Windows Server 2022. I don’t know that for sure.
Total time for download and installation is just a few minutes. You may need administrative privileges to install. On my Windows workstation I gave my user account higher than default privileges, which makes it easy to miss where elevated privileges are required.
FurMark used to be a good “max power” program for GPUs in the past, but stopped fufilling that role more than ten years ago.
