There's no guide and it's not simple to do.
Some thoughts.
The least of your problems is that there is no equivalent of Parallels' Coherence mode with Fusion on Apple Silicon Macs. It only exists on Windows VMs running on Intel Macs.
Fusion does have the ability to take and restore snapshots, but the process is manually initiated. If I remember correctly, VMware Workstation has the ability for non-persistent disks, which essentially revert the VM's disk at power-off. You may be able to accomplish the same thing by manually editing the .vmx file for the VM, but I'm not sure if the feature will work on Fusion.
Another option you might want to consider is to use a live Linux installation such as provided by Ubuntu. Those do not persist information to a virtual disk when they are shut down.
