I’m not sure why you would want to disable virtual memory mapping – it’s a built in function of the cpu, and pretty much essential when running an OS to properly isolate processes from each other.
Most operating systems allow you to disable virtual memory, so that your memory capacity is limited by physical memory. However, A processes address space is still virtual, and virtual to physical mapping is still happening.
A way to get what you want is to run an operating system that executes in Real Mode, such as DOS or Windows 3.0, or write your own.
The advantages of virtual memory far outweigh the disadvantages. Why do you want to avoid virtual memory.
