Partitioning Drive to Run MacOS26 w/ Apple Intelligence

What are the steps in order to safely partition a drive to run MacOS26 for testing on my main machine without corrupting the main machine, please advise? My machine is a Mac Pro M3 Max

Apple Intelligence/Foundation Models DO NOT WORK on Parallels VM.

I cannot afford to buy new machines. My current one is maxed out on GPU/CPU and memory.
